I'm installing a 1/4 HP 1.5 CFM rocking piston compressor with a single membrane diffuser pond aerator with a one day two settings timer in a one acre bowl shaped pond that's with a long 3' shelf. I believe this pond should be very easy to aerate because of it shape. My questions are how long and when should I run the aerator? I've seen posts that say all night, two times a day for 5hr, and 24/7, also how do I know if I'm doing it correctly? Is there an oxygen or temperature test to go by?
