Suitable for larger ponds, up to 16,000 litres, the Aquaforce 8000 is a variable flow solids handling filter and waterfall pump. The Aquaforce 8000 includes a variable flow adjuster, which controls the flow into the filter or the power of the waterfall, and can be used amphibiously. The second inlet allows a skimmer to be used to draw water from the pond surface, while the wildlife protection system prevents small fish, frogs and newts from being drawn into the pump.
