Metal Halide Bulb

[kennyishio]

I have a 250watt Metal Halide Unit with a old bulb. But I can't read what it says on the bulb. Should I get 10k,14k, or 20k bulb? In the end Ill have coral and nems. OW_O

Depends on your preference as to how you want the tank to look. Generally a 10K bulb is very white (some brands may even have a hint of yellow), a 14K is a nice mix of white and blue and a 20K is very blue.
