Metal Halide Questions VS. T5

[rastaangel]

I think it depends on were you plan to put the corals... if you wanted to do a full top to bottom SPS stock like I did on my 90g I would do 2x250 w/ T5 supplemental to get good light to the bottom. But then again thats around 10 watts/g which is fairly high... If you did 2x150 w/ T5 and kept the SPS to the top and zoos and others on the lower half you would be able to manage that
