Got a 75g bowfront Oceanic tank with PC
moonlighting. 2 10Ks and actinic. Been keeping those tight fitting glass covers off the top. They fit too well. Anyway, I got on of those 1/4 inch deep plastic ceiling light grids this weekend, with I'd say, 1/4 inch openings. They look great and fit right into the recessed area that the glass normally seats in, but subdue the light a bit. I can see slight shadows on some areas of my rock now.
Should I be concerned? Got leather fingers corals on the bottom of the tank, pumping xenias at the top, feather dusters on the top and middle, and a deresa clam on the sand bed, all been doing fine with either the glass or nothing. Would like more coral and know light is needed. Should I just closely watch the current inhabitants and go for lower light corals in the future? Really don't want to go with MHs.
