According to aquarium experts, the Cascade 1000 Canister Filter is the best freshwater fish tank filter on the market. The filter is suitable for tanks up to 100 gallons and can pump up to 265 gallons in a single hour.
The external system combines biological, chemical and mechanical filtration for guaranteed crystal-clear water and a safe, healthy environment for aquatic life. The floss pad removes the smallest particles of matter from water, while the coarse sponge promotes bacterial growth to encourage removal of waste, excess food and harmful chemicals. Four locking-clamps and an integrated O-ring provide the tightest fit possible. A self-priming button provides ease-of-use.
