What are fish tank filters?

Fish tank filters are devices necessary to maintaining clean water so your fish and plants can thrive. Filters usually consist of three filtration elements: mechanical, chemical, and biological.

Can an aquarium survive without a filter?

While it might be possible for an aquarium to survive without a filter, it's not recommended, especially if you have fish in the tank. A filtration system not only makes maintaining an aquarium easier, with fewer water changes required, but it also provides a better environment for both fish and plants.

Can a filter be too powerful for an aquarium?

Yes, fish tank filters can be too powerful for an aquarium and result in negative effects. For example, if a filter is too powerful with an overly strong water flow, it can cause excess stress to your fish. Filters that are too powerful can also potentially suck fish into the intake.

Can you over filter a fish tank?

Yes, you can over filter a fish tank if the aquarium filter is too strong and creating an excessively strong water flow. This can cause stress to your fish and even lead to nutrient deficiency in the tank.
