When connected to the inlet of your filter using any AquaMax Eco pump, surface skimmers effectively remove dirt, leaves, and pollutants from the top of your pond. These skimmers feature a stable base that can be filled with pebbles for extra support. The AquaSkim 20 is compatible with AquaMax Eco 4000 to 8000 pumps and can adjust automatically to a level of up to 100mm. The AquaSkim 40, on the other hand, is designed for use with AquaMax Eco 8000 to 20000 pumps and can adjust automatically to a level of up to 120mm.
