I've been in the hobby for over 8 months now and I think I kinda know something about something now. I would'nt call myself and expert or anything buy I think I know a thing or two. I have had regular compacts since I started my tank and I'm looking to upgrade to t5's in the next week. I have zoanthins, star polyps, green brain, orange sponge, frog tips, mushrooms, leather branch trunk in the tank as I speak. The leather branch doesnt look very healthy I think it's due to poor lighting. I have 75 gallon tank with a 20 gallon sump and refuge. 100 pnds of rock and over 60 pnds of sand. What brand of t5 lighting should I buy. Or is it possible to just switch out my Coralife Lunar Aqualight Deluxe Linear Strip PowerCompact Fixtures lights with t5s or am I going to have to buy a whole new fixture. If so what kind of fixture does anyone recommend and the should I purchase different bulbs for them ect.
