Pond Boss Forums AERATION Systems questions Does an aeration windmill need constant wind?

You may find all the air going to one diffuser as it is next to impossible to have the diffusers at the same depth with the exact amount of hose with the same water temperature,(all equals backpressure) keep in mind that as the wind varies that the cfm will constantly change and seek the lesser of the 2 backpressures. You may find them easy to set with a full wind and then constant adjustment as the wind fluctuates.If this windmill has two exhaust ports you would eliminate the above problem by running two seperate hoses.Goodluck and let us know how it works out.Ted
