Big Sister Filter

Big Sister Filter

A larger version of our popular Little Sister filter, the Big Sister is well suited for mid-sized koi ponds. With a larger spraybar and output, Big Sister is able to handle the higher flow rates larger ponds demand. Constructed of rugged fiberglass, the Big Sister is built to last a lifetime.

The Big Sister's dual chamber design and standard drain valves make cleaning a snap. Each chamber can be cleaned individually in seconds by shaking the filter media and opening the drain valve. The simple process saves countless hours of cleaning timeover a single season. Good for ponds up to 800 gal.
