Anyway, I was cleaning up for the coming holidays and started opening the windows and letting fresh air and sun in. Does this help our tanks or will it bring algae bloom? Here's a pic. Thanks.

I think it might mess with the ph of the tank but not really sure. I think I read that somewhere. I might be wrong but someone will chime in and set me staight.
