I'm actually looking at halides now. I used them in the past, loved the look and growth was amazing. I just wish I could find a MH/T5 hybrid fixture because two 250s won't cut it and two 400s is too much electricity.Reefbrites are great, Orphek bars too. If you want great coverage like t5s and color pop from Leds over a 120 gallon. I would absolutely go straight to the 36" Reefbrite metal halide unit with the XHOs attached front and back. Awesome coverage, spectrum, natural shimmer plus color pop.
Do you think the reefbrites with two 250s would be enough? I know when I had just four 250s over my 240 gallon the light wasn't evenly distributed.
