Self Cleaning Fish Tank Buying Guide


Cleaning a fish tank can be more complicated than cleaning the cage of a dog or a hamster. There are a lot of things that can go wrong when you clean your aquarium. That is why many fish tank owners consider a self-cleaning aquarium to be heaven-sent. These fish tanks can make keeping the integrity of your aquarium a breeze.

There are several components to a good self-cleaning aquarium. One of these is the type of substrate. You can choose soil, sand, or gravel, depending on the species of fish that you are going to put in the aquarium. Mineral-rich substrates are best as they can help sustain the life of aquatic plants.

Plants are important in keeping the water safe for your fish. Think of the roots of plants as natural filters and absorbers that draw harmful particles and chemicals away from the water. Aquatic plant life can also serve as hiding places for shy fish. If you put the plants on top of the fish tank, they can also serve as a nice décor.

Another component of a self-cleaning fish tank is a reliable filtration system. Plants alone may not be enough to keep the water clean. They will also need the help of a device to clean the water. There are also filtration systems that introduce oxygen into the water. This creates an environment that is more conducive to fish and other aquatic life forms.

Choosing the right life forms to put in your aquarium also matters. A fish needs plenty of room to roam around. Adding other aquatic species can also help improve the health of the aquarium environment. Nerite snails and Mollies can address the growth of algae in the fish tank. The Hoplo catfish is also helpful in gobbling up leftover food in the water.

What is a Self Cleaning Fish Tank?


Self cleaning aquariums contain all the right components that promote a self-sustaining environment for aquatic inhabitants. Contrary to popular belief, a self-cleaning fish tank will still require ‘cleaning’ or maintenance. The difference is that the cleaning and maintenance will be less frequent and less extensive than a non-self-cleaning fish tank.

Types of Self Cleaning Fish Tanks

If you are considering getting a self-cleaning aquarium or fish tank for yourself or as a gift to a child, then you need to choose between two systems. Your choice is dependent on how much energy and time you want to put in the system’s upkeep.

  • Gravity-based

These fish tanks come with a component that allows the movement of water from the bottom of the tank and out through a drain spout. Adding clean water into the aquarium pushes the dirty water down where it enters a tube. The ‘pushing’ effect of the clean water makes the dirty water to move outside. You can then collect this dirty water in a container.

Maintaining the aquarium is very easy with this setup. It requires only two things from you. The first is the addition of fresh and clean water. The second is to make sure that there is a container to catch the dirty water drained from the aquarium.

  • Garden Water

The second type of a self cleaning aquarium uses natural plants or small floating gardens. As we have already pointed out, plants do more than improve the beauty of your aquarium. They can also serve as excellent filters for the water.

What is great about this setup is that you will not have any issues with organic fish waste. The plants will utilize these waste products as fertilizers and allow them to grow. It is, thus, important to choose the right aquatic plants that will stay at the waterline. They will also need adequate sunshine and other maintenance measures to keep the plants healthy.

Why Do You need Self Cleaning Fish Tank?

People who buy self cleaning fish tanks often do so because they cannot allot a few hours of their time to clean and maintain their aquariums. These include those who are very busy with other things in their lives.

A self cleaning fish tank is also ideal for someone who has problems observing a strict aquarium cleaning schedule. Regular fish tank cleaning is a must to promote a healthy environment for the fish to thrive. That is why it is important to adhere to a cleaning schedule. If you always forget to clean your aquarium, then a self cleaning fish tank is for you.

The low maintenance nature of such aquariums also makes them good for children. The process of maintaining the integrity of the fish tank is not as complicated as an ordinary aquarium. It can also be a great tool for teaching kids to take on the responsibility of keeping their fish alive.

There are also people who abhor fish tank cleaning. They need to replace the water and make sure that it has the correct parameters. They need to scrub the walls of the aquarium to remove any algae buildup. In short, cleaning fish tanks is not fun. A self cleaning aquarium addresses that.

Frequently Asked Questions


What are the best fish for self cleaning aquarium?

The choice of fish for a self cleaning aquarium depends on the size of the tank. If you have a small 2-gallon tank, then a Betta or several pieces of Cory catfish, danios, white cloud mountain minnows, or bloodfin tetras will be fine. Larger fish tanks allow you to put larger species of fish or a greater number of small fish.

How does the self cleaning fish tank work?

This is a classic type of gravity-based self cleaning fish tank. The small rectangular aquarium comes with a clear tube on one of the tank’s sides. One end of the tube terminates near the bottom of the tank. The upper segment of the tube forms a 90-degree angle near the top of the fish tank and goes through that side of the tank. It then has another 90-degree bend that makes the tube look more like a faucet.

Dirty water almost always settles at the bottom of the tank. When you add fresh water into the tank, it pushes the bottom-dwelling dirty water into the opening of the tube. As you keep on adding new water, the dirty water gets pushed up the tube and out the tank. You will then need a container right under the spout to catch the dirty water.

Where to buy self cleaning fish tank?

You can buy a pre-made self cleaning fish tank or you can make your very own. In either case, you will still need to purchase the items from your favorite pet store. There are also online commerce platforms that offer a wide array of self cleaning fish tanks. Amazon and eBay are two popular choices. You can also visit the official website of the specific brand of fish tank that you are looking for. There are also pet care websites that offer these products.


It is important to understand that the best self cleaning fish tanks do not excuse you from ever cleaning your aquarium. They can keep the water clean. However, these systems will still require periodic maintenance. This can include checking the quality of the water to maintain the ideal temperature, pH, and mineral content for your fish. What a self-cleaning aquarium only does is that it lessens the frequency and reduces the intensity of cleaning the fish tank. At the end of the day, you will still have to keep a watchful eye on your fish. This is part of a pet owner’s responsibility.
