GC Tek media agitator retro kit · add a blower to any filter
Give your bead or sand filter the backwash it never had
Some filters ship without a blower but would really benefit from one. This kit is everything a pond keeper needs to add media agitation to a filter: the 2 HP agitator, the spring check valve and the fittings. Choose the version that matches your multiport — 1.5" or 2" — and tell us in the order notes whether the valve has female threaded or female slip fittings so GC Tek sends the right adapters.
