Is your pond turning murky, stagnant, or full of sludge? Stale water starves your fish of oxygen and lets unwanted bacteria and scum take over. This ½ horsepower electric aeration system pushes up to 5.3 cubic feet of air per minute straight to the bottom, oxygenating the full water column so your pond stays clear, healthy, and problem-free for years. Built for waters up to 1 acre, it runs day and night with almost no upkeep. As part of the broader ProLake 1 line, these systems are designed to clean and clear smaller ponds and lakes measuring up to 4 surface acres.

At the heart of this system sits a custom-built ½ HP compressor that moves up to 5.3 CFM of air down to depths of 50 feet. That air rises through the water and lifts oxygen-poor water from the bottom to the surface, breaking up the stratified layers that lead to fish kills and foul odors.
Oxygen is the single most important thing you can add to your water. With steady aeration, your fish and aquatic life live longer and healthier while your pond stays balanced.
This is the only aeration system on the market with a built-in timer, and it puts you in full control of when your water gets aerated. The UL Listed timer gives you exact scheduling so you decide the run times that suit your pond.
Everything is housed inside a durable, sound-deadening cabinet with ¾-inch walls, operating at a quiet 50/60 dB. Inside you will also find a pressure gauge to monitor performance at a glance.
Not all aeration is equal. Stagnant water in deeper ponds breeds bacteria and scum that harm your aquatic life and leave your water looking unappealing. Constant bottom-up circulation solves that at the source. Here is how this system stands apart from cheaper units:
Have a remote pond or an awkward spot for electrical hookups? No problem. You can set the cabinet away from the water's edge where power is easier to reach. Run a ½ inch PVC line up to 4,000 feet from the cabinet to a remote manifold, then route the airlines out to the Duraplate™ diffusers from there.
The compact cabinet measures 18"W x 18"L x 17"T, and an optional Level-Aer™ equipment pad (24" x 24" x 3") is available to set it on. This is a completely green, eco-friendly option that requires very little maintenance while running around the clock, even on cloudy days.
This system fits a wide range of water bodies up to one acre:
