Pond Boss Forums AERATION Systems questions Trying to Put Together an Aeration System

For that length run, I'd feel more comfortable running 1" vs. 3/4". There are barbed connectors that push into the poly to connect 2 sections together. Use good clamps on them tho. I had laid out poly in the hot summer sun, buried it, and next Spring it was pulling apart at the connectors. If I could, I'd dig the trenching and lay the poly when it was cool out, and cover it when it was cold out - close to freezing to make sure it was contracted from the temps. You'd be amazed at how much a long run of plastic poly contracts and expands with temp changes.
