Coral 10K, 14K, 20K?

In addtion to having actinics, what spectral range of MH bulb would be best for corals and their growth?

Most 10k lamps. The only exception would be the 175w Iwasaki 15k SE MH lamp. I do use 150w Pheonix 14k's only with good results. If I use AB 10k, I'm sure my growht would be faster.

I am currently using 20K MH's at 250W. I also have actinic lighting to supplement.

Should I be going to a 14K or 10K?

XM 10K's have a ton of Par!

For 20K Radiums look super nice and have the best par of any 20K bulb especially on a HQI ballast.

I assume you run SE?

if your also running actinics, go for 10K

14K if you just use the halide. i guess if you wanted you could also use actinics

20K if you like blue heavy light. i also know certain SPS and clams grow faster under 20K's
