CL1 System Filter Set Boxed set comprises of the CL1V multi bay Filter (from the skilfully designed "CL" range), with a 5000 Lph low wattage submersible Turbo Pump together with 15watt stainless steel UV Clarifier. Suitable for Koi Ponds up to 1,250 gallons (5,625 litres) or Goldfish ponds up to 2,500 gallons maximum (11,250 litres). As can be seen in the drawing the filter comprises of 4 bays (cloverleaf in shape), with pumped water entering the first bay (vortex), and thereafter taking a series of up and down flows through the remaining bays. The function of the brushes bay is to remove major solid particles which have not dropped out of suspension whilst travelling in the vortex bay. The Japanese matting bay serves a dual purpose of trapping tiny particles, but also as a biological bed. Finally the 3 foam layers to the last bay act to filter out very tiny particles before the clear water flows down through the “Aquarock” bay which forms the main biological bed.
