This is a beautiful stream fed pond, just under 1/2 acre in size with a small island close to one edge. It is approximately 165′ (50 m) long and ranges from 100′ (30 m) to 130′ (40 m) wide. The maximum depth of the pond is 9′, with the majority of the pond being approximately 6 to 8 feet deep which is fairly typical. There are several mature deciduous trees around along the shoreline of the pond.
The client was mainly concerned about filamentous algae growth, sludge accumulation and poor water clarity. The he algae blooms had been increasing each year, causing unsightly floating mats of algae. In addition, he also wanted to improve the water clarity and maintain the overall health of the pond.
After doing some research and reading articles on our website, Bryan decided that adding a subsurface aeration system would provide the increased circulation and oxygen levels required to help improve the water quality. Typically in most ponds, subsurface aeration is the most effective, long term solution to reduce the organic matter and sludge accumulated on the bottom.
Because of the unique shape of this pond, we determined that an aeration system with 4 diffusers would be required to provide adequate circulation.
Upon our recommendation, Bryan decided to add a 3/4 HP Rotary Vane Aeration System in a steel, fan-cooled cabinet. The new electrical outlet installed at the edge of the pond was 220 Volt, so we installed the appropriate compressor with this system.
Below are some pictures of the installed aeration system. We set the cabinet on a patio slab next to the electrical outlet. Although this system was installed at the edge of the pond, they can also be installed hundreds of feet away as well. Bryan’s electricians hard wired the plug inside the cabinet, so the that the compressor and cooling fan could be plugged directly into the outlets inside the cabinet.
