Three Diffusers with Gast Compressor

The Atlantic Water Gardens complete three-diffuser aeration system includes a commercial-grade Gast diaphragm compressor with three diffusers, weighted airline tubing, and all connections — a fully pre-matched kit for large pond or professional aeration installations. With a Gast compressor rated for continuous outdoor duty and three independent diffuser lines, this system provides thorough oxygen management across the entire water column of a large koi pond or commercial water feature.

Gast Commercial Quality in a Complete Kit

The Gast compressor in this system is the same commercial grade used in industrial aquaculture aeration — not a consumer pond air pump. It is rated for 24/7 continuous operation in outdoor conditions. Three diffuser placements cover the deepest zones, high-fish-traffic areas, and any corners or coves in an irregular pond shape. This kit is the ideal complete solution for established Canadian koi ponds where oxygen management has become a serious priority rather than an afterthought.

How to Use

Mount the compressor above waterline in a weatherproof location. Run tubing to three strategic diffuser positions and adjust flow on individual valves to balance coverage. Place one diffuser at the deepest point for destratification, and the remaining two in secondary zones. Run continuously year-round. Replace the compressor intake filter every 6–12 months. Inspect the diaphragm annually at spring pond startup.

Ideal for large Canadian koi ponds and professional water features requiring comprehensive three-zone aeration.
