Which metal halide bulb do you use?

[Thunderstruck]

I just purchased my first metal hilde unit for my reef tank, and was curouis what everyone thinks is the best bulb for fast coraline growth. I was think running a 14,000K 175W. Just wondering what others run...

 

[Mr James]

XM 250w 10k's and 20k's. I had an Iwasaki 6700k on an old grow out tank and although it was yellowish, the corals grew very well!!!

2 175w 10k Hamiltons
I also have 2 110w VHO actinics

 

[Harville]

Aqualine B 10ks (look more like 12k with higher PAR)

Can I run those Aqualine 250 watt SE 10k bulbs on m58 magnetic ballast? They say probe start only. A m58 is a probe start? Anyone know?

Aqualine are pulse start, M58 is probe start, sometimes they will work but it's not recomended.
