What type of lighting is best?

[Ryan]

I am running a 6 bulb T5 with ATI bulbs over my 20 inch deep tank and works great.

I would like to pop colour a little more so my plan is to down to 4 bulbs with 2 mars aqua fixtures and the end goal being 2 bulbs of t5 with ATI Blue Plus and 4 of the mars aqua.

I believe this will give me a good combination of growth and color, and pop.
