Glass Versa-Top blocking light?
So I have a new all glass versa top for my 36g BF. I noticed after a few days of use its got some white-ish residue built up on it from condensation/evaporation occurring in the tank. How much might this affect my lighting? Anything you guys use to treat the glass? I am afraid to use windex or anything for the obvious reasons but this is just going to get worse over time.
