We love this new system from Oase. It contains everything you need to create a perfect pond up to 15000 Litres.The pond filter included is the Biosmart 30000 previously labelled Biotec 10.1. This is a proven pond filter which works very well. The 36w UVC unit hangs out of sight onto the side of the unit and the whole system is powered by an Aquamax Classic 8500 Pond Pump.
