Cleaning glass at night to feed corals?

[Jaws]

I was just thinking about the amount of algae that is released into the water column when I clean the glass in the day. There's been a lot of discussion about feeding sps corals but a lot of the time the stuff you're feeding is either too large or you have to feed too much or spot feed in order for your corals to get their share. I was just curious, if you clean the glass at night when your sps polyps are fully extended, would that make any difference? Has anyone ever tried this or heard of anyone trying it? Could just be another stupid idea but then again maybe not.
