Oase Filtoclear are a superb range of pressurised pond filters. Filtoclear are available in four different sizes, suitable for different sized ponds. Filtoclear come complete with integrated UV clarifiers, to combat green water. Filtoclear are extremely easy to maintain. They have a third outlet from the filter, that can be piped straight to a drain. When you wish to clean the filter, you simply turn the dial on the top of the unit, and hand pump the centre lever. This method squeezes the waste out of the sponges, and purges it to waste. Filtoclear are also available in sets, with bespoke sized pumps included.
