I just bought this unit from topdogg on ebay, and was wondering if I should change out some of the t5 bulbs for better display on my 75 gallon reef tank with sps and clams. The stock t5 bulbs are 4x 54W T5 HO Actinic Blue:

Any thoughts?

I would definitely throw a KZ Fiji Purple in the mix. You could probably use the stock bulbs for a little bit but in the end I would change them all.

Depending on your MH bulbs I would run different combos with the T5's.

I would be inclined to do something like 1 ATI Blue Plus, 1 KZ Superblue, 1 KZ Fiji Purple and 1 UVL Superactinic. That will create a strong 20k look but pop almost all colors. Then run some high PAR 12k bulbs on the MH.
