Saltwater aquariums are probably the most rewarding sight in the fish keeping experience. Who doesn’t love a complex reef tank? There is a larger and more attractive selection of fish for saltwater, so you can create an actual work of art. But, as you would expect, marine aquariums are more difficult to maintain. The steps are basically the same, but there are a few particularities that you must be aware of. And it all starts with the tank. You’ll need all the information on saltwater fish tank prices, features, and negative aspects.

If you want a marine setup, a 30-gallon saltwater fish tank is an excellent choice. It’s large enough to create an amazing environment for your fish, but it won’t put a major hole in your budget. However, size is not the only one that matters, and not every tank is suitable to become a marine aquarium. Here is the list of the best 30-gallon tanks that are great for saltwater.

Best 30 Gallon Fish Tank Reviews 2020

This is an excellent aquarium to start our list with. It has an awesome design and is definitely built with the user’s comfort in mind. And it’s not even expensive, considering everything it offers. But let’s take one step at a time.

First of all, it really is beautifully designed. From the curved edges and modern hood to the clear glass back panel, it all looks great! The tank is made of strong, scratch-free glass, is compact, and will last a long time without any problems.

The LED lights are one of the major pluses of this aquarium. You have white LEDs for daytime and blue moon glows for the night, plus the benefit of color enhancing LEDs. The final effect is awesome. And there is one more cool feature when it comes to the lights. There are automatic sunrise/sunset and moonrise/moonset functions. This will create a relaxing environment for the fish, as it’s as close as possible to the natural pattern. Or you can program it to turn the lights off gradually if that’s what you prefer.

As for the other features, the submersible filter does an excellent job very quietly. It also has a return nozzle that you can adjust and decide if you prefer water to cascade into the tank or not.

This is the improved Biocube version that Coralife has created. And it’s an excellent product, with the automated features, great lights, compact filtration chamber, and cool design. As a bonus, it’s fully compatible with all the accessories that were launched with the previous version.

Here are the main aspects to consider before buying one:

#2 – SeaClear Acrylic Aquarium Combo Set

Rating
3.5/5

We chose an acrylic tank for the second place on our list, and you will see it has many great aspects weighing in its favor. First of all, Seaclear makes great acrylic tanks. They are light, clear, and long-lasting and a great choice for a saltwater aquarium. Not to mention this is a combo set, so it saves you a lot of trouble.

This particular acrylic saltwater fish tank is very strong and won’t bend or bow out in time. It’s light, easy to handle, and you would have to really make an effort to break it. This tank will stay in one piece for a long time, even if you have energetic kids or pets.

We love the modern no-edges look of this aquarium. Once you set it up, it will look amazing. It has a really clean and cool design.

The size and shape make it an ideal home for your fish. The great filter helps a lot when it comes to creating the perfect environment. It’s a three-stage filtration system that works very well, so the water will be clear at all times.

What could be improved is the light fixture. It comes with a black hood, but you need to buy the fluorescent bulb separately. Also, the openings on the top are pretty small, so that could be a little uncomfortable.

Here are the main aspects of this aquarium you need to consider:

Pros

Cons

What’s in the Box?

The box contains the tank, a reflector, the light fixture, but no bulb.

Take a look at this video to see one of these tanks already set up:

Our Verdict

This may not be a perfect combo, but it’s definitely worth considering. You still have to buy the other items separately, but in the end, you will have a good and awesome-looking aquarium that should last for many years.

#3 – Aqua Culture 29 Gallon Aquarium Starter Kit

Rating
4/5

If you think you should stick with the glass tank for your saltwater experience, this one is an excellent option. It’s a starter kit, and the elements are much better than you would expect for this price level. At this size, it’s not only great for seasoned aquarists but beginners as well. In fact, it would be a good idea to start with as large a tank if you can, especially if you want a marine aquarium.

Despite the price, the tank is made of thick and strong glass, so it’s long-lasting. It’s still not as bump-resistant as an acrylic piece, but it is scratch-free and looks great once you set it up. We did find a problem, however, with the hood. It’s made of low-quality plastic and not easily replaceable.
One of the best parts of this starter kit is the filter. It’s strong enough to get rid of any unwanted elements, so the water is always clean and clear. It is more than adequate, especially considering the price.

The LED lights may not be exactly high-class, but they look nice, especially at night time. Unfortunately, you may have to stick to plastic aquarium plants, because the light isn’t strong enough for live ones. That and the preset heater are the only negative aspects we have found.

But let’s break it down:

Pros

Cons

What’s in the Box?​

The package includes a Tetra internal filter, as well as food and water conditioner.

Take a look at the following video to see it out of the box:

Our Verdict

There are a few negative aspects to this tank, but they are not that major. Especially not at this price. To get a good starter kit at less than $120 is not bad at all. So, it’s definitely a good option.

#4 – Marineland (Aquaria) Glass Cube and Column Aquarium Tank

Rating
4.3/5

If you don’t want to get a set and prefer to buy all the items separately, this tank is a very good option. And that’s not a bad idea altogether; it may take longer, and you’ll need to study each item, but you can end up with the aquarium of your dreams.

The first thing that we noticed about this tank is how cool it looks. The shape really makes it stand out, as cube aquariums aren’t that common. If you also decorate it with style, it will be an eye-catcher for sure.

The tank is not only extremely good looking, but also very well built. The glass is high-quality, distortion-free, and it definitely won’t scratch. If you have a house full of kids or pets, you know how important that is. Accidental scratches can even happen while cleaning a tank, but not this one.
It’s a great option for a saltwater aquarium, especially because there are many lighting options available that will turn it into a marine wonderland. And once you place it on the stand, it will look amazing.

There is a negative aspect, though. It’s not quality-related, but more of a misleading situation. Looking at the box, you would expect to also find a lid inside, but there isn’t one.

So, let’s sum it up:

Pros

Cons

What’s in the Box?

Only the tank.

Check out this video to see how someone has set it as a reef tank:

Our Verdict

The missing lid is not exactly a nice touch, but since it’s the only negative aspect, it doesn’t weigh that much. Overall, it’s a great tank, so it’s definitely worth considering, especially if you don’t want a complete set.

#5 – Skrootz Aquarium Starter Kit 29 Gallon

Rating
3.7/5

This may not come from renowned manufacturers, but it’s a really good tank, and it’s definitely worth your money. You will be surprised by how much it has to offer at this price.

First of all, this 29-gallon aquarium looks great. It’s perfect for your home or your office. And with the rectangular shape and nice size, it will become a comfortable environment for your fish.

The glass is high-quality, and the tank will last longer than you may think. In fact, if you buy it on Amazon from Skroots seller, they actually offer a lifetime guarantee. That says a lot about how confident they are in this product.

We liked the low-profile hood and the lights of this aquarium. It also has an inward channel that makes sure the water stays clear. As for the LED lights, you don’t get a long tube, but a strip. It’s divided into 7 sections, with 3 white LEDs on each.

The filter does a good job. The heater also works well, but you cannot adjust the temperature. We see that with many sets lately.

Here are the major positive and negative aspects of this tank:

Pros

Cons

What’s in the Box?

The starter kit contains the tank, the hood, the filter and heater, the light fixture, and a few extra items: samples of Tetra food And water care and an eBook with complete and easy to follow instructions.

Our Verdict

You may be reluctant to try a product from a company you haven’t used before, but this one is worth trying. To be clear, this isn’t a perfect kit. But it’s more than decent, and the price is really attractive. The glass is strong, which is one of the most important things. And you can use the rest of your budget to make any upgrades you feel necessary.

#6 – R&J Enterprises Fusion Acrylic All in One Aquarium Kit

Rating
4/5

Back to acrylic tanks, here is a great combo from R&J Enterprises. This may be another manufacturer you haven’t used before, but this product is worth your attention. It’s an all-in-one 29-gallon kit and a very good choice for a saltwater aquarium.

The tank looks great, it really is beautifully designed, and if you pair it with the right stand, it will look amazing. The acrylic material is high-quality, so it’s also a resistant tank. They also added a support brace in the middle so it won’t bow. Not to mention you get pretty much everything you need to get your aquarium started.

As for filtering, it’s an aquarium with built-in filtration, and all the necessary accessories are included. You also get a 364 GPH aquarium pump, bio balls, and sponge filters. The fact that most items in the tank are built-in gives it a very clean and organized look. There is no external plumbing, so it’s aesthetically pleasing and easy to use.

Pros

Cons

What’s in the Box?

The 29-gallon acrylic tank, built-in filtration system plus accessories, a 364 GPH pump, Bio Balls, Filter sponges and LED Light.

Our Verdict

The price is a bit high, but it is an acrylic tank, and they are usually pricier. You get everything you need to get started, and it’s all good quality. With a few adjustments, like solving the open-top issue, you can end up with a pretty awesome aquarium and don’t have to stress yourself too much over it.

#7 – BioCube Coralife Size 32 LED Aquarium Reef Package

Rating
5/5

If you are planning the best reef aquarium, this package is a really good option. In even includes the stand. If you liked the BioCube listed above, you’re going to love this one!

The aspect is the most obvious advantage. The Coralife Cube has a modern and cool look, and in this case, you also get the stand, so you get the whole picture just by looking at the box.

As we said before, the BioCube is strong and will last a long time. The aquarium glass is thick, but also clear and scratch-free. The whole ensemble is easy to put together and get started. Honestly, it would be a shame not to turn this cool cube into a reef tank, and the marine landscaping will look simply awesome in it.

The filter and the pump are great, and the lights are also pretty good. As for the lid, there is plenty of space there to hide the heater and skimmer.

The only thing that needs improving is the stand. It looks great and has plenty of space for the fish food, extra filters, and everything else you may need. But It’s not very solid. More specifically, it’s not bolted together that well. You can fix that by removing the back panel and screw it in properly, but that shouldn’t happen with a new product.

Pros

Cons

What’s in the Box?

The BioCube, the stand, BioCube protein skimmer, along with a BioCube algae cleaning magnet and Coralife mini hydrometer.

Here is another nice presentation of the BioCube and how to turn it into an awesome marine environment:

Our Verdict

Overall, it’s a great package. But they really need to keep working on the stand to justify the price. Otherwise, people will just buy the BioCube separately, because that’s the start of the package anyway.

Things to Consider Before Buying a 30-Gallon Tank

Before you decide what kind of water you are going to put in the tank, you have to make sure the size you chose is best for you. If a 20-gallon is usually chosen by beginners, a 30-gallon aquarium can be considered the next step. So here are the things you need to consider before you buy one:

Where to place it

If your first aquarium was smaller and you are now thinking of making the transition to a 30-gallon tank, finding the right place for it will be a bit harder than the first time. Not by much, it’s still not a huge aquarium, but it’s important to realize that the extra size and weight will matter.

First, you need to know the exact dimensions, because they don’t all have the same shape. You must make sure it fits well in the space you have prepared and that the surrounding area won’t be affected by the occasional water splatters. Nobody wants that, but accidents do happen, so don’t place it where water can do much damage.

Then, it’s the weight. A 30-gallon is a lot heavier, so you need a stronger stand. It’s also not a good idea to move it once it’s filled, so decide on the ideal space beforehand. Since it will be heavy, safety is an actual concern, make sure the tank will stay where you place it.

The location is important for any tank, but if you are planning a marine one, take all the time, you need to find the perfect place. Saltwater tanks usually are spectacular, and it would be a pity not to display it correctly. The size of this tank, combined with the colors and the tranquility of the marine environment will make it a perfect therapeutical aid.

Glass or Acrylic

This is a choice you have to make regardless of the size of the tank. Glass was the traditional choice for aquariums, and there are good reasons it became so popular. It’s strong, clear, doesn’t change color over time, doesn’t bend or scratch. That last part is particularly important if you have kids or pets in the house. Or if it’s your first tank and you’re worried you’ll damage it.

Acrylic, on the other hand, is much lighter, so even a bigger tank will be easier to set up. You can even do it by yourself. Acrylic aquariums also have a modern and cool look. And they come in different shapes and dimensions. Since it weighs less, you don’t have to worry that much about the stand. But you do have to make sure it gets the right support so that it won’t sag in time. The downside is that it can scratch more easily. And when you clean the sides you need to use a special pad.

Price

This is an important aspect, no matter what size of aquarium you have in mind. It’s essential to know exactly how much the entire experience will cost. Apart from the initial costs for setting up the tank and stocking it, there are other constant expenses on the way.

But since setting up the tank is the pricier part, it needs a lot of attention. You must decide if you want a set or to but everything separately. Whichever option you choose, it won’t be perfect. But the details can be adjusted on the way, the main thing is to get a strong tank. You may have to pay a bit more for it, but if it has a warranty, it’s money well spent.

Type of fish

That’s the first thing you need to decide, because all the other preparations are made according to it. If you want a saltwater aquarium, it gets even more complicated. You can choose from the following: fish-only tanks, fish-only with live rock tanks (FOWLR), or reef tanks. You can even have a coral only tank. All these will look great.

Freshwater vs. Saltwater Fish Tanks, What Are the Differences?

These two types of aquariums are very much alike in many ways, but there are also some significant differences between them. So, it’s a good idea to get a clear picture before deciding which one you want to try.

From an aesthetic point of view, both marine and freshwater tanks can look phenomenal. There are many choices for both of them when it comes to fish and decorations. But aspect isn’t everything, and you need to know their particularities, so you create a healthy and safe environment.

As for the way they work, the basic principles are the same. Fish eat and produce waste that needs to be filtered. Ammonia needs to be removed in all tanks and there are a few filtration methods that are generally used: mechanical, chemical, biological, and ultraviolet.

Now, the differences.

You can place fewer fish in a saltwater tank, so you need to keep that in mind when choosing the dimensions. The bigger, the better is the general rule for aquariums, anyway, but there is also the matter of the costs.

Marine fish need a larger tank to have a stable and healthy environment. The water also needs to have higher PH values. Not just the PH but also the salinity and temperature must be kept steady. You will also use different substrates for marine and freshwater tanks. If your beginner freshwater aquarium had sand or gravel and rocks, for the marine one, you would need crushed seashells and corals.

Apart from the care and attention, saltwater fish tanks cost more. The water needs to be tested more regularly, and you need a more complex testing kit. If you also have corals, the lights need to be adequate. Filters need to be changed more often. Even the fish are more expensive for a saltwater tank.

These can seem a bit overwhelming, but once you get used to it and understand all the rules, it gets easier. If you think about it, it makes sense. Of course, it’s more difficult and expensive, you are creating a very complex environment, and you need to get as closer to the natural one as possible. But the results are spectacular and completely worth the effort.

Checklist for a Complete Saltwater Fish Tank Setup

A checklist isn’t important only for beginners. And, by the way, the 30-gallon is a great option for a first tank, if you are willing to spend the money. It’s also extremely useful any time you buy a new aquarium, especially if you are going from freshwater to marine. So, we made a complete list to make sure once you get started, you don’t have to buy anything else.

Here is what you need:

  1. Check the list above and decide which is best for you. Then find the perfect place for it, after considering all aspects.
  2. As we said before, choosing how to stock the tank should be the first thing you think about. All the rest, including the lights, depends on that.
  3. Skimmers, Filters & Filtration Equipment. There aren’t any special saltwater filters for fish tanks, but you must make sure that you choose a good one.
  4. Powerhead
  5. Live rock and substrate. It’s not as easy as some crushed seashells. Again, it depends on the types of creatures you are going to place inside the tank. Some of them may be more territorial than you think, so you will have to build them fun places to hide or sleep without feeling exposed. The result will also look very nice from outside the tank.
  6. Sea salt mix/saltwater and hydrometer. You need to learn how to make saltwater for fish tanks or even more specifically, what’s the best salt for a reef tank. It’s essential to get the water quality as close to the natural environment as possible. The salinity tester is something you will have to use regularly.
  7. Heater and thermometer. Setting and maintaining the water temperature is particularly important for saltwater tanks, as marine fish are more sensible. There are many types of thermometers to choose from, like a stick-on, a floating one, or even a multi-function remote digital sensor.
  8. Air pumps and air stones. You will need them if you use a counter-current protein skimmer.
  9. Test kits, additives, and supplements. The marine inhabitants of your tank are high-maintenance, as we have underlined before. You will have to make sure they find everything they need in the water, or you will have big problems. From calcium to vitamins and additives, you need to keep it all under control. This goes for saltwater aquariums in general, but if you also have a coral reef, it’s even more important.
  10. Tools and supplies you will use for maintenance. Setting up the tank is just the beginning, there are things you will have to do on a regular base, and it’s better to buy everything upfront. For cleaning the tank, you will need buckets and containers to remove the fish, a siphon tube, an algae magnet, nets. You also need spare parts for the items that need to be replaced from time to time. That will get easier as you get a bit of experience, you’ll know exactly what you need and when to restock.

Best Tank Accessories for Saltwater Usage

The filter

The filtering system is very important for any tank, but even more so for saltwater. The marine environment is more fragile, and you need a great filter to keep the water clean. There are many options on the market, but our recommendation for a 30-gallon aquarium is the Tetra Whisper EX Silent Multi-Stage Power Filter for Aquariums.

A digital PH meter is also very important, so you can keep the tank environment as stable as possible. Apera Instruments A1316 Premium Series PC60 5-in-1 is an excellent option, but if you feel it’s too expensive, there are more affordable ones on the market as well.

As for the skimmer, our recommendation is the Aquatic Life 115 Mini Internal Protein Skimmer, which does a great job, and it also has a pretty good price.

If you didn’t get a set or you did, but the heater doesn’t do a great job, this is an excellent option: Cobalt Aquatics Flat Neo-Therm Heater with Adjustable Thermostat.

As for test kits, the API Test Strips for Freshwater and Saltwater Aquarium do a pretty good job.

The salt you use is also important. We recommend the Instant Ocean Sea Salt for Marine Aquariums, Nitrate&Phosphate-Free, for a great quality-price ratio.

What Are the Best Fish to Stock a 30 Gallon Saltwater Aquarium?

Saltwater aquariums are pretty spectacular, so all the hard work you put into it will be well worth it. Marine fish and corals create an amazing environment you just get enough of. But it’s not always easy to decide on the best saltwater fish for small tanks?

First of all, it depends on how experienced you are. Some species are more sensible and need special care. Here are the fish you can start with:

  • Tangs
  • Watchman Goby
  • Chalk Bass
  • Damselfish
  • Dottyback
  • Clownfish
  • Coral Beauties
  • Wrasses
  • Butterfly Fish
  • Mollies
  • Royal Gramma Basslet
  • Blue Spotted Jawfish

You must follow the same rule as for freshwater tanks, make sure they are compatible, and won’t hurt or eat each other. As you gain experience, you can make different combinations. But stick to small fish, since a 30-gallon saltwater tank is still a pretty small one. If you want bigger and more spectacular fish you will need a bigger one.

Common Myths on Saltwater Tanks

Saltwater aquariums are more demanding than freshwater tanks. But that doesn’t mean you should believe everything you read online and get discouraged. We have made a list of the most common myths to see if there is any truth behind them.

Saltwater aquariums have to be big

There is some truth behind this statement. The fact is you can place less fish in a saltwater tank if you want them to have enough space and for the water to stay clean and clear. So, you get 20% fewer inhabitants compared to a freshwater tank. But the aquarium itself doesn’t have to be bigger if you choose fewer or smaller fish.

Freshwater aquariums are easier to maintain

This is very debatable and not that easy to answer. Both marine and freshwater aquariums can be high maintenance, depending on what you stock them with. You indeed need to handle maintenance a bit differently for saltwater, and it usually gets more expensive. But if you compare two basic set ups, you won’t see a huge difference.

The ‘Popeye’ effect is caused by microbubbles

That one is definitely wrong. There is such a thing as the Popeye effect, but it means your fish have an infection usually caused by ammonia burns.

Corals only need light

Light is very important for corals, but they also need planktonic protein a few times a week.

Useful Tips for your First Saltwater Tank Experience

Even if this isn’t your fish tank, if you are making the transition from freshwater to marine, you still need some tricks up your sleeve to avoid problems. You will face issues you didn’t have with your previous aquarium.  If you don’t have an experienced friend to guide you along the way, these tips will come handy:

  1. You won’t just be using tap water, you will have to add salt to it. And a 30-gallon tank holds a lot of water. So, you need a place to store the big amounts of salt or already prepared saltwater before you change it. And that place needs to be as close to the tank as possible, for things to run smoothly. You also need to store many other things, like testing kits, supplies. We guarantee that the stand you put the tank on will not be enough. Find that storage place before you start setting up the tank.
  2. Time is an important resource. You need to keep that in mind when you buy the tank and accessories. Because if things aren’t automated, you will have to do everything yourself. You may enjoy it for a while, but it’s a tedious work that needs to be done regularly and will take a lot of your time.
  3. You should be prepared for something right from the start: you will go over your original budget. No matter how well you plan everything and how much you research every aspect, you will spend more than you thought you would. First of all, fish sometimes die. Especially if you aren’t that experienced. And marine creatures aren’t that cheap. Even if you get an immortal anemone, you shouldn’t feel bulletproof, those can die, too. To avoid that, keep a close eye on the water, test it regularly, and don’t overdose anything. And try to create saltwater movement in the aquarium. Keeping the water as stable as possible is crucial.
  4. Remember that this is a long-term commitment. And it may take a while until the aquarium looks exactly like in your dreams. The environment you create inside that tank will grow more beautiful in time, and it will last for a very long time. But during all that time you need to keep investing in it, both money and time.
  5. Make sure the species you want are compatible. The last thing you want is to have your fish hurt or eat each other.
  6. If possible, make arrangements for a quarantine tank from the start. That way, if one or a few fish get sick, you can isolate them. It’s much easier to treat them that way.

Frequently Asked Questions

 

Do saltwater aquariums grow more algae? They do, which is one of the reasons a saltwater tank is not the best choice for a beginner aquarist. Both marine and freshwater tanks grow algae. But in a freshwater environment, you also have live plants, which feed on the same nutrients as the algae, thus preventing them from growing like crazy.

Do saltwater tanks need air bubbles? Air bubbles on top of a fish tank have a relaxing effect on the viewer, but you don’t need them in a saltwater aquarium. This is a conclusion that’s mainly based on the user’s experience rather than a report. The reasons we wouldn’t recommend air stones in a marine tank are the following:

  • Air bubbles can get trapped on the fish’ gills
  • They cause salt creep
  • When they break on the water surface, they can affect the lights

While some of them are debatable, the fact is when bubbles break, they remove salt from the water. It may not seem like a big deal, but since the saltwater environment needs to stay as stable as possible, it matters.

Do saltwater fish tanks smell? The answer is the same as for freshwater tanks. If they are properly cleaned, they shouldn’t smell. If the water in your tank smells, there are probably high levels of nitrates and ammonia. A good filtration system and regular water changes will prevent that.

Can I use ocean water in my aquarium? Clean ocean water is the best thing you can use in your tank. No matter how carefully you treat and monitor your saltwater, it will never really match nature’s product. That water will be rich in microscopic nutrients that are really hard to replicate. However, ocean water isn’t the same everywhere, and it’s not necessarily clean. You must carefully observe the area before using it. Make sure there are no pollution sources nearby and that it’s not mixed with freshwater.

So, while it’s an excellent idea, using ocean water for your tank isn’t always easy to put into practice. There is also the possibility of getting clean ocean water from another source. Some public aquariums and even water companies sell it, and the price isn’t that high. You will pay a bit extra, but at least you don’t have to spend time mixing it.

What is the best salinity for a saltwater aquarium? Checking the salinity is an important part of the saltwater fish tanks care. The best salinity depends on how you stock the aquarium. What you actually measure is the specific gravity. If you have a fish-only tank, then it should be between 1.024 and 1.026. If you also have corals, it needs to be between 1.025 and 1.028.

How long should I keep the lights on? Again, it depends on what you have inside the tank. If it’s only fish, then 8 hours a day is enough. But if you also have corals, leave the lights on up to 10 hours. Corals live in symbiosis with a type of algae that needs a lot of light, so to keep the corals healthy, you need to leave the lights on longer.

Conclusion

Fishkeeping is a great experience in general, but saltwater aquariums are particularly mesmerizing. There are so many types of saltwater fish for tanks to choose from. The colors are brighter and more diverse, you can add corals and really beautiful décor. If your first try was with freshwater, this is a step forward. But that also means it’s a bit more difficult. While the basic principles are the same, you have to be aware of the differences and spend more time (and money) making sure everything is taken care of. The saltwater environment must be kept extremely stable, for those beautiful creatures to thrive.

The 30-gallon saltwater fish tanks are ideal for a first-time marine aquarist. You can still use it once you get some experience, for small fish or one bigger one, or a side tank you can use for quarantine. We’ve said before that ‘larger is better’ is the general rule for fish tanks. Well, saltwater aquariums need to be even larger. And they are also very addictive, so once you get used to the marine environment in your house, you will definitely want to upgrade it.
