On my 75 gallon hopefully soon to be sps filled tank i just upgraded my lights from power compacts to an 8 bulb T5 fixture. I think I may have picked out the bulbs incorrectly though.

I got 4 blue plus bulbs, 2 aquablue special bulbs, and 2 purple plus bulbs all from ATI. The only thing I dont like about this combination is that all my macro algae now looks brown instead of a dark green. I even pulled some out of my sump where it looked a dark green, and once in my tank it looks really ugly brown. What bulbs would you guys switch out to make the greens look a little better. Thank you.

My 8 bulb setup is like this, front to back

Blue plus
Blue plus
Blue plus
Blue plus
Aquablue special
Fiji purple
Blue plus
Blue plus

I like the blue color that this setup gives me, my only recomendation would be getting rid of one of the purples on your setup, and replace it with a blue plus or an aquablue special

Pull an Aquablue for a GE 6500k.

I would pull both Aquablues before I touched a purple bulb. I have found the Purple bulbs do MUCH more for color then the Aquablue bulbs.

I personally don't like Aquablue bulbs for anything. They are extremely white and wash colors out.
