Lighting time on advice

[Wayne]

My tank is about 20" tall and the T5's are currently about 4-5" above that and the metal halides are 7-8" above. When I build the canopy this week all the lights positions will be reversed.

If you guys recommend having them higher I need to know tonight because tomarrow I start cutting

In my tank I have cabbage coral, pulsing xenia, frog spawn, mushrooms, candy cane coral, zoas, flower pots, kenya tree, GSP, toad stools. I also have a clam. All of the low light stuff is near bottom and off to the sides. All the higher light stuff is center and positioned higher.
