How To Clean A Fish Tank Filter & Why You Should

How to clean a filter in a fish tank and why you should clean your aquarium filter. Fish tank filters are an essential piece of aquarium equipment. The primary purpose of having one is to keep the water clean, oxygenate it, and provide a habitat for beneficial bacteria.

Most equipment slows or clogs over time. This is true with filters too. All that dirt and debris has to end up somewhere. Eventually, the filter clogs and needs cleaning. But, how safe is it to clean the filter? Will it disrupt the ecosystem?

Is It Safe To Clean A Fish Tank Filter?

Yes! Cleaning your aquarium’s filter is safe if you use the correct steps. Remember, filters are home to beneficial bacteria that contribute to the health of the aquatic ecosystem. Incorrectly cleaning the filter removes the bacteria and does more harm than good.

So, do not clean the filter with tap water. Why? Tap water contains chlorine and other harmful components that disrupt your fish tank’s ecosystem.

Tap water may destroy the beneficial bacteria that live on the filter. These colonies of bacteria took quite some time to build up and, if eliminated, would be detrimental to your aquarium.

Why are the beneficial bacteria good for the fish tank? These bacteria are essential for biological filtration. They break down harmful chemicals and toxins and release less harmful ones.

For example, beneficial bacteria break down ammonia, which is dangerous, into nitrate, and then break down nitrate into nitrite, which is safer in small quantities. It’s all part of the nitrogen cycle.
