A pump draws water down through the gravel to be able to come up with approving conditions for a successful biological filtration. The gravel filters and eliminates a lot of debris from the fish tank water. These filters are always easy to sustain, but with time they can fill up.

The external filter performs all the vacuuming and filtering outdoor of the tank and keeps the unfiltered water separate from clean water. These filters are always suitable especially for small fish tanks as they need regular cleaning and also can maintain the tanks aesthetic value. They pump water in and out of the container providing a fresh source of constant clean water. These are the best types of filters on the market but are also the costliest. They include:

Consequently, they are suitable for containers that require a high level of filtration.

  • Power filters
