Title says it all, I need to get a cover for my new 55gal. It came with some covers and lights, but I'm not a fan and I am going with a different light setup. It is 11' deep and 23' long section(2) I was going to cut plexiglass and put handles on them(to move the cover when needed) but figured that it could warp due to the heat from the lights. I then thought of using some mesh cover but again thought it would warp/bend. Anyone have any ideas for me to use.
