How should I light my 20long (30"x12"x12"), I would like to be able to keep most any coral anywhere in the tank, hears what I’ve been thinking...

1. Four 24watt HO-T5 lamps
Pros- lots of light, lasts a long time, uses little electricity, less heat, lots of options for lamps
Cons- don’t know the light spread over 30inchs, no “shimmerâ€

Of those three options, I would (and personally have gone with) go with option 1. I think that the perfect combo nowadays though is MH with T5HO supplementation.

Which corals are you looking to keep? Any plans for acro's or Croceas/maximas? If not, have you considered 2x65 watt PC fixture? Just an idea. On a 12" deep tank it would be great for just about any low-medium light corals.

Go with the 150 watt Aquamedic pendant with a lamp around 14,000k. I think you will like it. It will be less intense towards the ends of the tank but not too bad. I had a 150 watt Hamilton Reefstar over my 20L and it worked well.
