T5 Retrofit advice

[mbs]

I'm putting together a t5 retrofit for an acro frag tank--24w t5's around a hydra52 hd. The frag tank is 30 x 20 x 12, the retrofit will be mounted in a floating canopy. I've bought the hydra and a 2-T5 retrofit from BRS, and I basically have 2 questions.

1) Should I add another 2-bulb retrofit, for a total of 4 bulbs? I obviously don't need more light, I just am looking for a balanced T5/Led look, shadow prevention, etc. Will 2 T5's give me good supplementation, or should I spring for 4?

2) Anyone have any convincing bulb combo arguments? I've bought a coral plus and a blue plus so far.

Thanks for any input.

I would go with 4 to give the extra color combos. If you find 4 too many just remove 2 bulbs.
