I have a Hammer and a Frogspawn that both seem to be having issues. They are of the branching type and both colonies have 2 heads each about 1.5 to 2 inches across at their widest point. Both have been getting very white in color. We all know that the hammer typically has a green color but it's nearly white right now and the Frogspawn was a pink/brown color and it's also getting very "bleached" I have 2 40w 48" actinic and 2 175w 10K mh's. The tank is 80 gal's and all of my parameters seem to be in check Nitrates and nitrites are around 0 consistently, Ammonia has never registered over 0. Phosphates are 0, PH is 8.2 and alk is 2.3. I dose with B-inoic. Feed Phyto every other day. My Bubble coral is growing out of ctrl and my leathers, shroom's, green star polyps and zooths are growing out of ctrl. These 2 have slowly but surely expanded less and less. They booth seem to look their best when the actinic are on but the MH's are not. Are they getting too much light? Now the hammer looks like it's starting to get hit by some small tuffs of hair algae around the crown of the coral. I really want to try to save these 2 but I can't figure out the problem.
