I agree. I would not turn off my skimmer unless doing so in the daytime cycle. Oxygen levels drop at night . Respiration is co2 which is why if you take a ph reading in the morning it will always be lower. Like others say it's wear and tear on the pump . It's a safety factor I just don't want to be without... Leave it on all the time ..
