well i had some bleaching on my sps and finally decided to screen the tank. I put 3 sheets on it and slowly took them off. IM down to one sheet now and i have started growing coralline well. I have never grown any in this tank with the 250w halides and a shallow tank. I believe it was too much light for it to grow. I also had this issue with my old tank which grew corals out the top of the tank but didnt grow a spec of coralline. So if you want more pinks and purples on your strongly lit halide tank just throw a couple screens over it and it will take off. just wanted to share because ive asked why i couldnt grow it for years and never got the answer that worked.
