I know I probably wont be using my refugium on a brand new tank for awhile but I want to pre-plan as much as I can to save the headache in the future, right now after testing out the light spot I wanted to ask if I should be worried about light spillage. Im using the fiji baffle kit on a 29 gallon aqaurium as my sump, unfortunately not all the pieces they provide are blacked out and a lot of light is making its way into the filter sock section. Is it worth the effort to black out that side? If so any recommendations for a marine safe paint on acrylic or other options, maybe plastic sheet not sure.
