Pond filteration is one of the most important components in maintaining a healthy and balanced ecosystem. Quality filteration equipment is necessary to maintain optimum water quality. Aquascape PondSweep® pond skimmers are large enough to tackle ponds up to 1200 sq. ft. of surface area making it a great choice for larger ponds. PondSweep’s® patented skimmer bellows creates suction on the surface of the pond keeping the pond surface clear from debris. PondSweep® includes an easy-to-clean filter mat reducing filter maintenance.
