Humidity and Heat Problems in 20 gal Long

[Popeye]

you can go to home depot or lowes and get a piece of plexi glass and cut it yourself. just score it several times with a razor blade and the snap it. i suggest you get a piece big enough to cover the entire top then drill holes or cut it down to size to get your humidity right.

Find a store who do custom glass and plexiglass work and order yourself cover what fit on top screen (inside plastic rim) and cover 2/3 of it ... That cost me maybe 7$ and looks more esthetic that aluminum foil

Thanks for the tip on plexi glass. Ive been using aluminum foil also. Going to Lowe's today to pick up a piece.
