Pond Boss Forums AERATION Systems questions My new aeration equipment

The restriction valve built into the Vertex diffusers is what is causing the little higher air pressure (abt 1psi). I would close the open valve that is wasting air and send that air to the diffuser to increase the size of the boil and create more water movement. In your location and pond size you would only need to run the aerator 8-10 hrs per day for 0.8 ac and size of your air pump to get adequate turnover per day.
