Water evaporates and if you have a airstone in there the bubbles spray water all over... Have you ever put water or sprayed a hot incandescent light bulb by accident with something and had it explode ? The same would happen with the florescent light... That will be a huge mess and contaminate your whole tank..
Yea I have the same stand and same tank as you.. the stand that has a overlapping top that the tank sits on.. How well has you stand held up ? I noticed mine if I get 1 drop of water on the top and let it sit for a second or two it literally makes that pressed saw dust board bubble.. even though its powder coated black... It sucks !! Just gatta be extra carefull when doing water changes and stuff not to get water on the top the tank sits on because it goes UNDER the tank and I found the only way to get it from under there and ruining the board is put your mouth there and suck on it to get the water out lol
