Kyle,
Very nice!
It is amazing how much humidity you can cut down with a good lid on your tank.
I had egg crate on all of my tanks, while it was great for keeping the fish in the tank, it doesn't keep the water in the tank. I am really cheap, and I have a lot of tanks and the thought of buying glass for lids was overwhelming. Not to mention raw edges on the glass, etc. I was beside myself to figure out how to use the existing egg crate, I knew that I just needed some type of barrier. I use acetate a lot at work to put over plans, it is a thin plastic like you see on the front of report covers, it is available in 48" wide rolls. We cut a piece the size of the egg crate and used shipping tape to hold it on. This has worked for me,I have also used shrink wrap and a shrink wrap that has an adhesive on it.
Cichlid Power!
