Buyers Guide – Best Self-Cleaning Fish Tanks

Before you start searching for the best self-cleaning fish tanks, it is imperative to know how actually to identify the best one. In this guide, we discuss several criteria that you must keep in mind when selecting the ideal self-cleaning fish tank for your purpose.


There are basically three types discussed in this article. The first one is the filter-driven method, where water is circulated through a filter system.

The second one is the water garden type, where plants on top of the aquarium feed on the fresh excrete and nitrates created in the water by the fish.

The third type is the gravity-based system, where water with excrement is siphoned from the tank when new water is added. They are the smaller aquariums in this article.

Which type you choose depends on your own likes and needs.


The size or the capacity of a fish tank is an essential consideration when you buy one. Don’t just buy it because you like the looks but rather keep the following in mind;

An easy rule of thumb is to reserve a gallon of water for every inch of fish you want to keep. If your aquarium you want to have is smaller than a gallon, you will only be able to go for a tiny fish.

The second criteria for tank size are the space you have available for an aquarium. A smaller aquarium can easily fit onto your desktop, whereas a bigger one will have a dedicated place where it will fit.

If you take these factors into consideration regarding the size, you should be pretty safe.


Before buying an aquarium, you should find out what the carrying capacity of the thing is on which you want to put the aquarium. Not doing this might end in chaos!


Fish tanks keep up with innovation and have come a long way since first introduced. The most significant advantage we have seen in the development of fish tanks is the introduction of easy cleaning fish tanks.

Using them nowadays make keeping fish a lot easier, and they can be used as a demonstrative tool to teach children a lot about nature.


Does Fish Tank Water Have To Be Treated?

Change 10% of your aquarium water on a weekly basis or 25% every two weeks. Replacement water should be at the same temperature as aquarium water. Treat tap water with a water conditioner to neutralize chlorine and ammonia before adding it to the aquarium. Change the filter cartridges at least once a month.

What Are The Disadvantages Of The Self-Cleaning Fish Tanks?

– Algae outbreaks are very common in these fish tanks, and you won’t always have room to add Algae eating fish, snail, or shrimp to fix the problem.
– Fish waste often builds up quickly in small gravity-based tanks, and the siphon won’t catch all the debris.


Cleaning a self-cleaning tank will just take a minute; it’s easy enough for even a child to do. It just needs a few cups of treated water every second day. You can collect the dirty water in a container as well and then use it to fertilize or water your garden.
