We love this new system from Oase. It contains everything you need to create a perfect pond up to 15,000 litres. It replaces the previous Biosmart 30000 Set but now contains a bigger pump (11,500lph vs previous 8,500lph pump) and is £50 Cheaper than the set sold last year - Great news I\'m sure you\'ll agree! The pond filter included is the Biosmart 36000. 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 11500 Pond Pump.
