What is a Nano Reef Tank?
A nano reef tank is, in essence, a tiny bit of the sea that fits perfectly on your desk. It includes everything that the larger average saltwater tank holds, but on a much smaller scale.
In general, these tanks have a capacity of fewer than 30 gallons.
This tank is ideal for anyone who wants to create a reef aquarium, but do not have enough space to accommodate a large tank.
With its small and compact size, you can put a nano reef aquarium on your desk or any shelf where you can conveniently marvel at the beauty of their reef construction.
Unlike the standard reef aquariums, you do not need a dedicated stand to support the weight of your nano reef tank.
You can put it anywhere on a stable and flat surface.
And guess what? It is also easier to cultivate a reef in a smaller space.
On top of it all, stunning more minor details are easier to observe than in large aquariums wherein your eyes might miss them.

How to Find the Best Nano Reef Tank?
Contrary to popular belief, finding the best nano reef tank is not a walk in the park. Even though I have narrowed down the options, there are still a few things that you have to put into consideration.
Luckily for you, I have added this shopping guide to make your shopping experience even more convenient.
Nano Reef Tank Kit Components
Nano reef tanks are mostly sold as complete kits, with some components and equipment being accessories to the aquarium.
These tank components are vital since they will help you run the aquarium as well as reduce the overall costs.
If you are planning to buy a kit, make sure that it has an LED lighting system and a filter. You might want to look for a timer or remote control for managing the LED lighting system.
Some kits also come with a heater.
The nano reef aquarium you are planning to buy should suit the coral type you are keeping. Photosynthetic corals, for instance, need a lot of lights, which means a shorter aquarium works best in this case since it is better in optimizing the light source.
Shape of Nano Saltwater Tank
There are different shapes of aquarium on the market today, including bow-fronted, cylindrical, hexagonal, cubed, rectangular, and many more.
If you do not have a clue on what is the best aquarium shape for your space, take note of these tips:
- Overly tall aquariums can be difficult to clean or decorate. Moreover, the light might not reach the tank’s bottom, which limits coral growth.
- Some aquarium shapes may restrict the quantity of fish that you keep. And, they can also limit the fish’s movement.
- The larger the aquarium’s surface area, the easier its aeration is going to be. Keep in mind that removing harmful gas is essential to the health of your marine life.
- Certain tank shapes, like hexagonal and bowfront aquariums, may distort the view of your stunning reef.
It is natural, for most of us, to go for the cheaper alternative. Everyone does it!
While the price is undoubtedly a crucial factor, it should not be the only thing that you have to put into consideration.
So, take some time to research different nano reef tank models. And do not forget to read the best nano reef tank reviews above, until you have the right one for you.
If the price of your preferred nano reef tank is pretty high, try to look for another unit with similar equipment and features.
At the end of the day, the inhabitants of your aquarium are sensitive and precious. That is why you should buy them the best haven you can afford.
