osvrat - okay more information helps, just like going to the doctor. Adding to my post above, your second biggest error was not having an adjustable pressure relief valve on your compressor manifold. An adjustable relief valve allows you to determine the pop off pressure based on the needs of your unique situation.
Certain pond conditions and water quality causes diffusers to clog at different rates. Evidently your pond has a high clogging tendency for diffusers. Choose the diffuser with a los clogging rate (usually rubber or vinyl membrane) and BUY an adjustable pressure relief valve and use it. I normally set the valve for full pop off at 15psi for rotary vane pumps. This small item protects the most expensive part of the aeration system - the compressor.
