Hozelock Aquaforce (15000LPH) The striking new Hozelock AquaForce 15000 comes complete with an exclusive Wildlife Protection System, which protects small fish, newts and frogs from accessing the pump. The large surface area of the cage, ensures that the maximum amount of waste is collected and pumped to the filter system. The Aquaforce 15000 can work amphibiously, while the second inlet allows a skimmer which can draw water from the surface of the pond to be used. The variable flow control adjuster, allows the flow of water to the waterfall or filter to be adjusted and also regulates the volume of water drawn from the second inlet. The Wildlife Protection System reduces the risk of damage to common pond wildlife.
