I was aerating 24/7 and have cut bact to 12 hrs a day because this time of year my elec bill can get up there , seems like the ac runs 24/7. My schedule is 3 hours from 11 am to 2pm, i chose this time because it seems to be the hottest part of the day and i was trying to circulate some of the cooler water that is deeper. I dont know if this is right or wrong and that is what im trying to figure out. then i aerate from 930pm to 630am, my thinking there is those are the coolest hours of the night and i want to circulate the water then. my pond is .6 acres and averages 5.5' deep. my aerator is a 3/4hp compressor and 2 diffuser stones, one toward each end of the pond. I have noticed no difference in the pond but its only been a couple of weeks, is my thinking on track? thanks in advance
