How Does the CF-500UVMKII Canister Filter Work?

Unfiltered aquarium water enters the CF MKII Series Canister Filter and passes by the U.V. Sterilizing Bulb flowing down the stack of vertical cylinder cutouts to the bottom of the CF MKII Filter. Then water is pushed up through the filtration media compartments; the bottom compartment first, the middle compartment second, and the top compartment third. The filtered aquarium water then returns from the CF MKII Canister back into the aquarium. 

The CF-500UVMKII has a built-in 9-watt UV sterilizer to help kill algae spores and bacteria, promoting crystal clear water.
