14K Metal Halide Bulbs

[Saltysteve]

I am running a 14k Metal Halide bulb on a standard ballast. I am going to buy another 14k but I am wondering, they are Hamilton 14K's with less PAR rating than others, should I add 10k HO's for added coral growth or does 2 x 14k MH work well?

Most seem to be running HO Actinics with their MH lights but I do not think that is needed with 14K's.

Any input would be appreciated!

Thanks
