200 gallon reef tank metal halide help!

[staceyd72]

For a 36-38" tall tank you most likely will want 400W, maybe supplement with T5 or VHO, as mentioned colour temp is a personal choice. I find growth and colour is good with a 14K bulb.
I have a 250G with 2 400W(used to be 3) at 28" tall in Lumenarc (large) reflectors and supplement with four 165w 454VHOs, works for me.

I use 'sakis(6500K) on the frag tank, ugly to look at but grows coral like weeds
Back in the day we used to use the 'sakis on the DT, with the proper Eye ballast they actually look very nice.
