11 Flow-through filters A flow-through filter has the advantage that the water is strongly enriched with oxygen due to the special array of split sieves and filter mats. This is necessary especially dur- ing summer and in case of dense stock with animals and plants. Flow-through filters usually provide a larger chamber for biolog- ical filtration, they therefore allow for even more surface. Flow-through filters make sense especially in case of pond sizes above 10,000 liters (2,642 US gal.). Innovative compact filter systems for all ponds  low maintenance, space saving filters with multiple efficiency for clear water in ponds  sera pond UV-C System 55 W (includ- ed with the sera KOI Professional 12000 Pond Filter) for effectively re- moving bacteria and floating algae  split sieve technology for permanent removal of floating particles up to a size of 200 µm and oxygen enrichment  fine mesh sponges for removing float- ing algae and cloudiness  biochamber including matala mat and sera siporax pond for cleaning the water biologically Further advantages:  low phosphate and nitrate levels due to quick removal of dirt and waste parti- cles  easy installation and little maintenance effort  suitable for ponds up to 20,000 liters (5,284 US gal.) water volume and Koi ponds up to 12,000 liters (3,170 US gal.) (sera KOI Professional 12000), or for ponds up to 40,000 liters (10,568 US gal.) water volume and Koi ponds up to 24,000 liters (6,340 US gal.) (sera KOI Professional 24000) sera KOI Professional 12000 / 24000 Pond Filter Water intake Stainless split sieve 200 µm Oxygen enrichment Dirt chamber Fine mesh filter sponge Waste water removal valve Matala mat Biofiltration with 10 l (2.64 US gal.) sera siporax pond Water outlet
