regular output t5's

[corbett_n]

I tried lighting forum with some good ideas but definate answers, so I will try it here. I have two coralife t5 (not Ho) 30" double bulb fixtures. Does anybody know what kind fo output these regular 10000k 30" bulbs produce. Would it be enough for me to have 3 10000k 18w t5 (not Ho) for a 30g reef tank (mushrooms, poylps, easy corals)?

Yes, you'll be able to have easy corals with with that lighting with that shallow of a tank. I've got corals growing in deeper areas on a 300g tank with just two 4ft T8NO bulbs.

I have the same fixture, but 36". It's a dual 21w T5 fixture, also with a crappy 20" 28w PC light over a 30g and I have a decent amount of corals in there. Polyps, zoos, mushrooms, hammers, frogspawn, crocea clam, kenya tree, colts, acro frags, cabbage, and some others, I can't think of right now. I wouldn't reccomend it though for anything other then polyps, shrooms, softies etc. I do plan on upgrading when I get a different tank. It's more of a frag tank.
