Hello,

Which metel halide should I be running. I am keeping fish, leathers, and animines(SP)? Will any of these be better for non algea growth?

10k
14k
20k

Thanks,

Randall
 
i would go with 20K bulb as it is used mainly to bring out the vibrant colors or your corals. A 10K bulb is mainly used for the rapid growth of corals & yes that also includes algae. However, algae will grow with these two bulbs either way you just have to keep your phosphates and nitrates on check.
 
The best advice I can give is visit stores and friends with systems and look at each one. No one can tell you what you like or dislike. I think 20k is a bad choice as it is very blue and generaly has poor PAR and growth. It also depends on what you intend to keep long term, how your system is cooled, if you plan to supplement with actinics or not etc. There are so many bulbs, ballasts and combinations its impossible to blindly recommend any one thing.
