Aquarium Filters for Fish Tanks
An aquarium filter is absolutely critical when setting up a tank. Reef tank filters tend to be larger and more complicated than those used for fish-only aquariums, but aquarium filters for saltwater fish are similar or the same as those used in a freshwater aquarium. There are many styles of aquarium filters, such as canister filters, hang on the back filters, corner filters, fluidized bed filters, and undergravel filters. Each of these aquarium filters has its pros and cons and are used for specific reasons.
