SunSun 264-GPH 5-Stage Filter with U.V. Clarifier

The SunSun HW-504B external 5 stage canister filter is ideal for tanks up to 75 gallon. It handles up to 264 gallons per hour. The SunSun HW-504B includes filter pads, hoses and all the parts you need to get started. The four flexible media trays allow you to add other filtration media such as SunSun's activated carbons, ceramic rings or bio-balls (each sold separately) to achieve excellent mechanical, chemical and biological filtration. A built in 5 Watt UV sterilizer helps control algae spores/bacteria and promotes clear water. Since the SunSun HW-504B's pump is locate inside the aquarium, there is no need for priming or fill the filter with water before operation.
