What are Self Cleaning Aquariums?

Self Cleaning Aquariums are the tanks that use the principle of Aquaponics to grow plants in the same tank used to keep fish and other water animals.

It is a wonderful example of sustainable living where plants are grown using fish waste as fertilizer and inhaling the CO2 released by the fish for their photosynthesis process.

Plants, in turn, provide a favorable environment to grow bacteria to remove nitrates and nitrites present in the water. The whole process helps to filter the water and keep it clean for the fish to enjoy a healthy life in the tank.

The biological self-cleaning process also prevents aquarists to spend their valuable time cleaning and maintaining the aquarium.

In the tanks where the biological cleaning concept is not used, they use a gravity pump to remove impure water from the tank and fill fresh water to keep the tank clean all the time.

So, in either of the above two methods, self-cleaning fish tanks have automatic cleaning mechanisms that help users to reduce the manual cleaning of the tank and save their valuable time and energy.

Advantages and Disadvantages of Self Cleaning Fish Tanks


The biggest benefit of self-cleaning fish tanks is that they reduce the efforts needed to frequently clean the tank.

Even the simplest traditional aquarium too will require you to remove hose, filters, and empty the water in a bucket, and so on. The whole process can be quite cumbersome in some of the more complex set-ups.

So, if you are busy and cannot spend time cleaning the tank and still want to live your passion for fishkeeping, no-clean fish tanks offer a wonderful alternative.

You may still have to clean the tank manually once in a while yet the frequency of such cleaning requirements would be too low to cause any discomfort.


Though most of the reputed brands of self-cleaning fish tanks offer auto cleaning mechanisms. Some of them may lack the features claimed while selling the product.

So, it is very important to know some of the flip sides of the no-clean tank, as well.

Self-Cleaning Aquariums Need Cleaning

Though less as compared to the traditional ones, self-cleaning tanks still require cleaning. To know the exact cleaning and maintenance requirement, you need to refer to the manual of the particular product that you select.

The tanks using biological methods of water cleaning help in growing the beneficial bacteria. This process may get uncontrolled in case there is excessive growth of algae in the tank.

And if you do not have enough algae-eating pets, you may find the water inside the tank extremely dirty and toxic. It may eventually force you to clean the water immediately to provide a safe environment to the fish in the tank.

In the aquariums fitted with the gravity pump, if the pump does not remove all the fish-waste, the tank will get filled with excessive toxic substances, not quite healthy for the fish to survive. In such situations also, you may need an emergency cleaning of the tank.

And mind you, as the tanks are not particularly designed for manual cleaning purposes, it is much more difficult to clean these tanks compared to the traditional ones.

Quick Toxins Build Up in Small Sized Tanks

Many aquarium tanks have sizes up to 5 gallons. The waste generated by even a few fish in such small tanks can increase the toxicity of water to dangerous levels in a quick time.

The bio-cleaning tanks absorb the ammonia from the water to keep it clean. However, tanks with gravity pumps do not have this feature. Even the bio-cleaning tanks have a limited capacity to clean the toxins in the initial stage.

Changing Water Quality

As the self-cleaning tanks are designed for auto cleaning of water, they do not have traditional filtration systems or have a very basic filter to remove dirt.

So, if the growth of favorable bacteria is restricted due to any reason, it will become very difficult to remove toxins from the water. Even in the most efficiently controlled tanks, if the water quality deteriorates and becomes cloudy or has high algae growth in it, it becomes extremely difficult to maintain the right quality of water.

This situation is particularly problematic in the water garden tanks which depend solely on the plants to absorb toxins.

The quality of water may undergo significant changes with changing crop conditions, as well, and may pose serious threats to the aquatic life in your tank.

Lack of Oxygenation

It is not only removing the toxins that are important for the healthy growth of the aquatic animals but the dissolved oxygen in the water also plays an important role in providing them a healthy environment.

Gravity base tanks give more problems related to low oxygen levels as they do not have any water circulation system. This causes water to stagnate and grow harmful bacteria that can be very dangerous for your pets.

From this aspect, water gardens are better compared to the gravity pump types of arrangements because they deploy pumps and some of them even use filters.

Getting the Best Self Cleaning Aquarium- Buyers Guide

So, we reviewed here the top 6 best self-cleaning aquariums. You can select the one that best suits your specific needs after going through the detailed buyers guide provided below.

Type of tank

There is broadly two types of self-cleaning fish tanks viz. gravity-based and water-garden type of fish tanks. They are differentiated by the maintenance system each one of them adopts.

The gravity-based system uses a pump to remove dirty water. You can collect the used water in a container and replenish the tank with clean water. The pump is strong enough to remove water but not too strong to take out fish along with the water.

The water garden arrangement as the name suggests has a garden at the top of the water inside the tank. The fish waste generated in the tank is used as fertilizer to grow the plants.

So, to find out which of the above two options is better for you let us consider them one by one.


You should select the gravity tank in the following situations:

  • If you want to change the water quickly and easily.
  • You are fine with doing maintenance of the tank once or twice a week.
  • If you have a garden or plants where you can use the spent water of the fishbowl.
  • If you want a simple fish tank/bowl for your kids without any complex system.
  • If you don’t want any mess during cleaning or maintenance.
  • If you want to connect many small tanks with the sump filter.

Water gardens are recommended in the following situations:

  • If you want to grow plants utilizing the waste generated by the fish.
  • If you are interested in learning/teaching the recycling system of nutrients and want to do a small-time DIY project.
  • If you want a compact plant cum fish tank in your small office space.

Tank Capacity

Having finalized the type of tank, the next step is to decide the size of the aquarium that you would like to select for your purpose. It will depend on the type, size, and a number of aquatic pets you plan to house inside the tank. As a rule of thumb, each one inch of a fish should have one gallon of tank capacity.

Further to this, you should also keep space for the necessities like heaters, filters, air stones, and plants, etc. The tank shouldn’t be too small. It should allow for the free movement of the aquatic pets inside the tank. So, ideally, for fish, the tank size should never be less than 5-gallons while for other pets like snails, etc, less than 5 gallons may also be quite appropriate.

Overall Volume or Space occupied

If you have space constraints, gravity-based systems are highly preferred options. They do not take up a lot of space.

The water gardens, on the other hand, can be quite large considering the plants, pods, and the lighting system as a part of the overall arrangement. Select the size that best fits in the location where you plan to place the aquarium.

Selecting the Right Fish/Pet

This is one of the most important criteria in setting up your self-cleaning fish aquarium. Fish requiring a high amount of maintenance may be troublesome for you to manage in the no-clean tanks.

You should go for the species requiring minimum to no maintenance like a guppy, betta or goldfish, etc. Apart from the type of fish, you should also study the kind of environment suitable for these types of fish and whether you will need a heater to maintain the right temperature for them.

Besides, you should also learn about the kind of food for each type of fish and also the quality of water for their healthy growth.

Q: Do We Need to Treat the Water to be Used in the Aquarium?

If you are a novice and using the aquarium for the first time, it is better to go with the plastic plants as the real plants will also require their part of care for proper growth and nourishment. It may be quite complicated for you to deal with both the living organisms in the beginning.

Q: Can I Eat Plants Grown in A Water Garden?

A: Though many aquarium brands claim it to be safe to grow sprouts or herbs in the fish tanks, it is not the best idea to consume these items as a healthy food alternative.
