AerMaster Pro 1/4 HP Pond Aerator Bottom Diffused Aeration

System for Ponds up to 1.5 Acres

A healthy pond starts from the bottom. The AerMaster Pro 1/4 HP Pond Aerator is a high-performance bottom-diffused pond aeration system designed to improve water quality, increase dissolved oxygen, and support a balanced aquatic ecosystem. Delivering 2.6 CFM of airflow, this electric pond aerator effectively circulates water in ponds up to 1.5 acres and 20 feet deep, eliminating stagnant zones and promoting healthier conditions for fish and beneficial bacteria.

Unlike surface aerators that only agitate the top layer of the water, the AerMaster Pro uses bottom-diffused aeration to circulate the entire water column. This continuous movement transfers oxygen throughout the pond, helping reduce algae growth, eliminate foul odors, decrease organic sludge and muck buildup, and improve overall water clarity.

Built for residential ponds, farm ponds, fishing ponds, and recreational lakes, the AerMaster Pro delivers dependable, energy-efficient performance season after season. Every component is engineered for durability, easy installation, and years of reliable operation.
