I have an approximately 1/3 acre pond with a dual diffuser aerator running from a gast 0523. I also have a windmill powered aerator but it is very sporadic given a large tree line to the west of my pond and I’m probably lucky to get 1 CFM ona good windy day. I’d like to run the aerator part time to save electricity costs and I believe my air pump is sufficiently large enough to do so on a pond my size. My question is, if I were to run it 12 hours a day would it be better to run 12 hours consecutively or break it up into intervals. Currently I’m running about 3 hours at 4 evenly spaced intervals. Also is there a better time of day to run. I’ve heard oxygen levels are lowest at night. Would it be best to run at night and not during the day or vise versa or does it really just not matter. What impact would of have on the wear and tear of the pump. Are frequent shorter intervals better or worse than longer less frequent intervals? Thanks.
