I have a 1.5 acre pond with 5 diffusers running 24/7 on a 1hp pump.
The electric bill is over $100 per month and would like it cut it down.
Just wondering if using a timer on a 12hr cycle during the day (7am-7pm) would be the best bet.
The OP said he would leave his off during the day when it is hottest, I thought that is when you would want it on?
