The Hozelock 1580 Aquaforce Filter Pump is suitable for ponds up to1000 litres and is a solids handling filter as well as a waterfall pump. Versatile and controllable, this 25W Aquaforce can be used flat or on its side and the case has an integral carrying handle which makes it easy to lift into or out of the pond. It has a large cage surface area which reduces cage clogging and improves water purity. Pond water is drawn in through the cage grille which filters out coarse solids up to 6mm in size. Smaller particles can be eliminated by fitting the supplied clip-in fine mesh filter tray which reduces the inlet diameter down to 2mm and affords the best possible protection for pond wildlife such as small fish, newts and frogs, preventing them from accessing the pump.
