I would like some feedback on what metal halide hqi bulbs work best for sps coral growth. I have a good amount of ora acro frags and would like to see considerable growth. I have the current usa twin 250w MH and 4 54w T5. Im also using a galaxy ballast that i hard wired to the current fixture. I switched from the stock 10k's to phoenix blue 14k the color looks great but coral growth is reduced. Any feedback would really help
