SunSun HW-704B 9W UV 4-Stage External Canister Filter

The SunSun HW-704B External Aquarium Filter system utilises a multi-stage approach to filtration. Filtering aquarium tank water through four internal layered baskets filled with assorted filter media material provides extremely thorough biological, mechanical and chemical filtration. This Canister draws water into the filter through an inlet tube and returns crystal clear water via an outlet tube (both supplied). The outlet tube is fitted with a spray-bar to help increase oxygen aeration levels within your tank. These filters are absolutely ideal for freeing-up space within your tank and provide a huge internal capacity for filter media, making them suitable for larger volume tanks.
