The frequency of cleaning your aquarium filter depends on several factors, including the filter type, tank size, and stocking levels. As a general guideline, mechanical filter media should be cleaned or replaced when they become visibly dirty or clogged, while biological media should only be rinsed gently in tank water when necessary to avoid disrupting beneficial bacteria.

Can I use a freshwater filter for a saltwater aquarium, or vice versa?

It is generally recommended to use a filter specifically designed for the type of aquarium you have. Freshwater filters may not be able to handle the demands of a saltwater environment, which requires more efficient biological and chemical filtration. Saltwater filters are typically designed to handle the unique challenges of maintaining water quality in a marine ecosystem.
