Can I run a skimmer only a few hours a day?

[MarkoD]

So I've got a 200 gallon system that's pretty lightly stocked with fish.

My skimmer is rated for 1000+ gallons

Right now I have my skimmer running constantly and it pulls out a lot of skimmate but I don't think it's constantly pulling because its so oversized


My question is: would it be just as good to just run the skimmer twice a day for a couple hours?

Airation shouldn't be an issue without the skimmer running
