All depends what you're planning to use for mh bulbs I suppose. The ATI Blue+ have tons of par and add some great colour to a tank. You could go with a whiter/brighter mh and get your blue from the t5s.

At the moment the fixture has 2 250w 10k MH's(brand unknown) when I replace them prolly gonna go with the phoenix 14k's. I'm in the dark when it comes to T5's tho(sorry for the bad lighting pun lol)

Beautiful fixture. Have seen it in person. Have fun with the lighting combos.

Thanks! Im running 1 kz fiji purple,1 kz coral light 2, 1 geisemann aquablue,and one geisemann actinic plus. Along with my 10kmh it has a crisp white look with a hint of blue. Very happt with the color and am happy I got the look i was going for in my first shot at it:biggrin:

Cheers
