For some reason all my LPS' seem to be bleaching. Not dying, they eat. I guess all of thin is an over statement, the Trumpet and Candy corals seem to be fine. But a huge green Brain and a rose brain have lost most of the color and now my red Lobo seems to heading that way. I've done all the test, I feed 1 or 2 times a week with DT's and Cyclopeez. Calcium is great all SPS' have great growth. I am a little behind on water changes but I evaporate 20 gallons a week on the 150 during this freaking heat. Any clues?
