When you say they are not doing well. What exactly is the problem?

20K lighting depending on your Ballast and the bulb type my not be enough light. Same with the 14K. PAR ratings on these high K lights can change drematically based on the ballast.

acroporas' tentacles used to be longer and the tip starting to bleach out, currently I am using 400 watts hamilton ballast and 14k bulb and the other one is 400 watt PFO with xm 20k bulb they are both 3 months old bulbs.
