Hi,
I'm converting my reef tank to fishonly with live-rock and thinking of replacing my 4-400w MH to T-5s. I really don't need the lighting for 400w MHs anymore. I had lost all of my stock due one of my bulkheads leaking while my family and I were away on a trip. I'm assuming the tank was dry for a few days for all was dead when we got home. Not to mention burned out pumps and such.
Tank had been up for over 7 years but somehow the nut to the bulkhead had losened over time. Lesson learned, should periodically check the nuts on bulkheads. Especially when you have them mounted on the bottom of the tank.
I've finally gotten the motivation to restart up my tank and going the fishonly route this time, was too painful to lose so many corals. So anyhow...
My tank dimensions are 10'L x 3'W x 30"H.
My questions:
1. Will 8 - 54W 48"ers, 4 on each side (right & left), be enough to illuminate the full width of my tank (Front - Back)? Perhaps not enough spread, need more lights?
2. Will it look 'darkish' at the sand, perhaps I'll need to override the blubs to 80w?
Again this is for a fishonly with live-rock, no intensions of growing SPS or clams again. Just after low heat, low power consumption, and awesome lighting to bring out the coloring in the fish.
EDIT:
I'll be using a retro-kit with individual reflectors, either IceCap or the newer TeK (when available).
Any recommendations/options and blub selection will be more than welcome.
