Lighting on a frag tank

[JeffyT]

Im currently running a jbj 20 gallon long frag tank. i converted the All in One with an overflow into a 30 gallon sump.

my question for you RC'ers.

I have 2 AquaticLife T5 HO 24 Watt fixtures. Ones longer than the other but both house 2 24 watt bulbs.

I am currently running ( Front to Back) Blue Plus. Coral Plus. Purple Plus. Coral Plus.

The fixtures have the lights sitting about 5 inches off the water. The fixtures stand on the pegs/legs that came with the light. Is this enough distance?

Do i need supplemental LEDs?

What can I do to optimize this setup?

What are you planning on growing and do the T5's have individual reflectors?
