How to Clean Your Betta Fish Tank’s Filter

In maintaining a clean betta fish tank with healthy fish, one of the most important things you can do, if not the most important, is to clean your fish tank filter regularly. Generally, cleaning a betta fish tank filter weekly is a great starting point – it only takes a minute, and your betta fish will definitely appreciate it!  If you don’t feel like cleaning your fish tank, I suggest you get this Self-Cleaning Betta Fish Tank – it’s awesome and you never have to worry about cleaning your tank or deal with filters and pumps again.

Cleaning a Mechanical Filter
Obviously, your cleaning method and frequency will depend on the size of your tank and the type of filter you use. My tank has a pretty standard mechanical filter that has a foam (or sponge) pad that sits inside it. It’s really simple to clean.

First, make sure to unplug the filter. Mechanical filters can burn out easily if they are not covered with water. The next step is to simply open the tank, take the foam (or sponge) filter out, and run it under cold tap water. I like to rub it against itself slightly to get most of the dirt out. You can then easily put the sponge or foam pad back and plug your filter back in.

In order to clean the other, harder to reach areas, it’s a great idea to get a filter cleaning brush. The filter cleaning brush will allow you to reach hard-to-get-to areas that are unreachable by hand, such as the casing and tubes.

Betta Fish Bowls with No Filter
If you are trying to keep a betta fish bowl, then obviously you do not have or want a filter. If that’s the case, make sure to change the water regularly – otherwise the ammonia build up will eventually harm and kill your betta. There is one Betta fish bowl I really like that actually does have a filter, but still looks like a bowl.

Cleaning Chemical Filters
If you have a chemical filter, the only real cleaning that needs to be done is a weekly swap out of the carbon. Depending on the condition and location of the tank, once a week may even be too frequently – you can wait until the water gets cloudy. Remove the carbon, use a filter brush to scrub the hard to reach areas, and then add the new carbon when you’re done.

Other Notes on Cleaning Your Betta Fish Tank Filter
There are some other factors that can influence your cleaning schedule. Depending on your environment, and the environment of the tank your using, you may have to clean the filter more frequently. If you see a build up of algea, due to having the tank in sunlight (or in keeping the lights on in the tank), then it’s important to clean the filter more frequently and also scrub the tank walls. This not only will let you see and interact with your betta fish, but will also let him live a longer and healthier life.
