- Hang On & Canister Filters
Hang on filters and Canniser filters can be used in Freshwater and Saltwater aquariums.
We recommend using HOB (hang on back) filters and canister filters only when using a hosptial tank and are not ideal to use with saltwater aquariums. For freshwater they work great for polishing the water and removing impurities, but in saltwater they can quickly increase your phosphate and nitrate in your system.
