The PolyGeyser beadfilter is automatically self-cleaning without moving parts or electronics, contains EN (Enhanced Nitrification) media that offers 50% to 100% greater nitrification than standard beads, and is capable of providing mechanical filtration down to 5 micron particle size! The PolyGeyser filter can be installed underneath or above water level. Any low amp water pump (like Oase, Messner, Red Dragon, and Sequence) can be used as a circulation pump. The PolyGeyser has the lowest possible pressure loss because it uses no multiport-valve. Inlets and outlets are 3".   It’s already being used in aquaculture, and now it’s ready for koi ponds.
