Designed for serious pond keepers and lake property owners, this 6.7 CFM pond aeration system delivers professional-grade dissolved oxygen for water bodies up to 3 acres in surface area and 50 ft. deep, giving you the air output needed to support fish populations, reduce algae blooms, and prevent winter fish kills. At the heart of the kit is a 1 HP oil-free compressor that produces up to 6.7 CFM at 1,660 RPM with energy-efficient 745W operation, paired with overheat protection and an anti-backflow safety valve so the pump runs reliably through long aeration cycles. Four 360° nano-bubble diffuser plates release dense, fine bubbles that rise from the pond floor, circulating water from bottom to top and oxygenating deep zones where stagnation and low oxygen typically cause fish kills. Each diffuser connects through one of the 4 included 100 ft. weighted self-sinking hoses, so airline routing is straightforward without needing extra anchors or buoyancy adjustments. A built-in timer lets you cycle the system on a schedule, lowering electricity costs while still maintaining oxygen-rich water, and the complete kit ships with all connectors needed for setup. Whether you manage a private fishing lake, a koi pond, or a large ornamental water garden, this turnkey aerator gives you the equipment and capacity to keep deep, multi-acre water bodies healthy through every season.
