Last night my husband and I were trying to figure out why the electric bill jumped $90 last month. Some of it is due to fans, dehumidifier, and air conditioner as well as having extra company but we were wondering about the pond pump. So he was watching the meter while I unplugged and plugged back in the pond pump. The pump is a Sunterra 4300 gallon. Is there a way to figure out the cost of running it? Yeah, it was my own fault, I plugged the pump into the timer slot for the lights and the lights to run all night! Duh! Now, is the bacteria in the pressurized filter done for? Does this mean I start all over for bacteria? Hope not because I have the rest of this month and the month of August before frost comes so I don't believe there'll be enough time to restart the bacteria.
