It's my understanding that the oxygen from the skimmer keeps the pH up a bit. At night the pH is naturally lower as algae, plants and stuff that are giving off oxygen during the day absorb oxygen at night and give off C02 and this affects the pH.

So I'd just leave it on. But, that said, if the thing keeps you up at night, I don't think it would cause major harm if it were off for a few hours.

I was just giving you a reason to leave it on.
