Experiment completed. A number of months ago I posted a question as to the difference between MH HQI 14000K and 20000K bulbs. The feedback from this forum was that the 14 had more PAR and therefor more beneficial for coral. I decided to test that theory and can now, without a doubt, support that opinion. I will spare you a lengthy thread but sufice to say after switching back to the 14000K bulb yesterday I note a definite improvement in the health of my coral. Yes, 1 day later! This after running the 20000K bulb for 6 weeks after running the 14K bulb for the same time period. Although the 20 gives off a superior light to enhance the green pigments the 14 has what my corals need and love. :)

thanks man you just saved me $140-160 i was just about to order a couple replacements, but I have noticed that my corals responded much better when I changed my 20ks to some 14s I had lying around. I had the same thing happen my corals freaked. I thought it was due to the fact that I had not changed my bulbs in 7-8 months. In a couple days I had 6 candy canes start to spilt, my xenia split 3 times!!!!, a zoa budded three times, and a random monti had considerable growth within a week. I also noticed a lot more coraline on my glass.

The lower kelvin rateing you go the better for your corals. 65000K would give you growth that you would not belive but would render your tank unattractive and a yellowish green color. 20K is way to blue for my liking. I am acctually thinking of going 10K when I replace the 14K that came with my halide.
