Well all but 1 of my SPS that I have gotten in the last 6 months slowly lose there color from the bottom up when I put them into my tank except for the ice blue tip which is doing great. The SPS that do brown out don't seem to die I have had a purple bonsai for 6 months that has still not regained its color but seems to be growing. I am wondering what I am doing wrong any help would be greatly appreciated.
