Four Diffusers, Ready for Large Ponds

The Atlantic Water Gardens complete four-diffuser cabinet system is a turnkey commercial aeration solution — a Gast compressor in a weatherproof outdoor cabinet, four diffusers, weighted airline tubing, and all connection hardware included and pre-matched. For large residential koi ponds, commercial water features, or any installation where comprehensive oxygen management across multiple zones is essential, this is the complete answer in a single package.

Maximum Coverage, Professional Grade

Four independently controlled diffuser outlets mean you can address the deepest zone, multiple fish congregation areas, dead-zone corners, and any supplemental oxygenation needs — all from a single weatherproof cabinet. The commercial Gast compressor is continuous-duty rated and runs reliably through Canadian winter temperatures, ensuring your fish always have oxygen access even under two feet of ice. Cabinet protection keeps the compressor clean and dry, reducing maintenance intervals and extending motor life substantially compared to unhoused air pumps.

How to Use

Install the cabinet above the waterline in a secure outdoor location with access to a GFCI-protected circuit. Run four tubing lines to strategic diffuser positions across the pond. Use individual outlet valves to balance airflow to each zone based on depth and fish load. Run continuously year-round. Annual service: replace compressor filter and inspect diaphragm at spring pond startup.

Ideal for commercial koi facilities and large residential ponds over 50,000 L in Canada requiring complete turnkey aeration.
