Pond Boss Forums AERATION Should I aerate? to aerate or leave well enough alone!

I 2nd Theo's suggestion of running air line. You can buy 1" poly tubing in 500' spools, no need to have a fitting underground. You need to bury it, you have no idea how much squirrels like to chew on it........

Winter aeration needs to have the diffuser set at 1/4 the total pond depth, near shore so that there is open water all the way to the shore so anything that might go for a swim can walk out of the water and not have to climb up on the ice to get out. That helps prevents super cooling of the pond water.

Yes a winter diffuser can be used to keep ice away from around a pontoon boat or dock. We did a test the past few years on a public lake for a client and they can keep a boat lift on each side of the pier and the whole pier ice free. We used 3 diffusers and a 3/4 hp rotary vane compressor to get the cfm needed to make the waves to keep the ice from forming. One diffuser is in about 18" water the other 2 are in about 40" of water.

Buck Dog, your pond is a prime candidate for an aeration system. One diffuser placed at 18 feet for the late Spring/Summer/Early Fall and one placed at 4'-5' depth for Spring/Summer/Fall/Winter aeration. You probably will have to use a 2 diffuser airstation in shallow water because you will shut the single disk air station in the deepest part of the pond off and you don't want to run more than 4-5 CFM through a single Vertex membrane diffuser. Yes to the Gast Rotary Vane, either a 1/4 hp or a 3/4 hp. You will have to make a manifold with ball valves on each of the air station lines so you can adjust the air flow to get equal air flow to both deep and shallow air stations when running both at the same time.
