Saltwater aquariums are very popular, and this is all thanks to the fact that saltwater fish are very colorful. Pair them with some beautiful décor elements such as an underwater castle, and you will build a fantastic aquarium that is going to blow you away every time that you look at it. However, many hobbyists make the mistake of thinking that a saltwater aquarium is easy to maintain. This is not always the case, and you need to make sure to search for the best marine aquarium to make your job easier. Here is where we come in.
Today we are going to share with you the top 10 best saltwater aquariums and list their most important features. While an aquarium that is filled with saltwater species is tricky to maintain, the effort is all worth it. You should make sure to stick around for the end because we are also going to explain what are the best features to look for in a reef tank and answer the internet’s most asked questions about saltwater fish and aquariums. Now that we got that out of the way let’s jump right into it.
We are going to kick things off with the budget-friendly MarineLand 5 Gallon Portrait Glass LED Aquarium Kit.

You can get the marine aquarium in the 5 gallons or 13.5-gallon size options. The 5-gallon choice is perfect for saltwater fish, but we do need to mention that a smaller fish tank requires more maintenance work.

The massive size of the reef aquarium makes the tank perfect for hobbyists who want to add more species to their ecosystem or go crazy with the decorations. There is more than enough room. However, the size is not the best thing about the NUOVO SR-60 Pro, and instead, it is the fact that it sells as an all-in-one package.

Aquarium Buying Guide
If you are new to aquariums, then finding the best one might sound like a daunting task. However, you don’t need to worry because we have your back. We are going to present the top three most important features that a saltwater aquarium needs to feature to be considered a premium product.
Glass vs. Acrylic
The first thing that you need to do before searching for the best marine aquarium is to ask yourself if you want glass or acrylic. Glass is the cheaper option, and it doesn’t get scratches quickly. However, there is a downside. Glass will shatter pretty easily. On the other hand, we have acrylic that is more expensive but also very durable. In addition, acrylic aquariums come in various shapes.
The Weight of the Aquarium
What you should never overlook when deciding what aquarium to buy is the weight. Even though a 10-gallon fish tank might weigh in at only 20 pounds when empty, it can quickly go over 150 pounds when filled with water. This is why you might want to consider going for one that is bundled with a dedicated stand. The Reefer Deluxe Concept 170 is an excellent choice here.
Filtration and Maintenance Tools
If there is one thing that you want to avoid when setting up a new saltwater aquarium, then this has to be finding a sound filtration system and getting all the extra maintenance tools that you need, such as a pump, for example. Therefore, we highly advise you to go for premium saltwater aquariums that ship with their own filtration system and maintenance tools.
Frequently Asked Questions
How much does it cost to start a saltwater aquarium?
The cost of setting up a saltwater aquarium depends on your plans. Do you want a big aquarium that can hold up to 20 species? If that is the case, then you are probably going to spend somewhere between $600-$1000 for a high-quality fish tank. You can always go for something smaller and pay $200-$500.
Can saltwater tanks use tap water?
Even though tap water goes through a purification process so that we can drink it, it’s not safe for saltwater tanks. The reason behind this is that the purification process doesn’t get rid of all the chemicals that can harm fish. We want to mention that fish tanks such as Marina LED Aquarium Kit are equipped with special tools to make tap water safe.
How small can a saltwater tank be?
Generally, the saltwater tank can be as small as you want it to be. However, it’s always better to go for a bigger tank. This is thanks to the fact that a large marine ecosystem will do a better job of handling the daily fluctuations in water quality. Not just that, but a larger saltwater tank doesn’t require too much maintenance work. You can do it only once per week.
