T5 lighting enough for a 90g

[Myka]

You will get lots of opinions on this subject! Personally, I'm a diehard metal halide fan.

On my 90 I have 2x250w DE halides w/ 2x39w T5HO supplementals. The T5s are from a 3' tank I used to have, they are just temporarily (for the last year LOL) placed on top of the tank until I manage to set up the 48" Tek Retrofit I bought 8 months ago.

Anyway, I used to be an LPS collector, and swore I would never go back to prissy, finicky SPS. Well, my fixture is too much light for most of my LPS to show their best colors so the SPS have been moving in in plague proportions. All my LPS are on the sand or off to the side away from the halides. Having said that, I know lots of people with 250w halides that have LPS near the top. Go figure. Everything else aside, mine have best coloration with less light than SPS want. My Hammers and Frogs I gave up on and moved into a tank lit by T5s.
