With all the talk about frozen air lines probably due to frozen condensation or water in the airline, has anyone had one freeze, contract and shut down where it entered the pond surface ice? I've run winter aeration for years and can't say I've ever had it happen. Could it be because I run them continuously, the air pressure keeps the air line from contracting? I'm also thinking the black color may have a low albedo effect when the sun is shinning, allowing melting around the hose? I've seen this around my pier in winter too.
Anyone?
