Just since yesterday my mature Devil's hand leather has developed raised yellow spots on it and is not extending polyps, the giant anthelia looks really bad and is shedding pieces, xenia doesn't look happy and other leathers don't look very good but no spots. Bubble Tip Anemone, Zoas, Galaxea, Hydnophora, Montipora digi's, Bubble coral, mushrooms, GSP, inverts and fish all look fine. This is a 40 gal tank with a 20 gal sump/refugium that has been set up here for about 3 months though all the sand was from a very established tank and has a few pieces of established LR along with reef bones which have been in the tank since I set it up, probably 70lbs or so total. The fish load is a Maroon clown, small yellow tang, neon goby, scooter blenny. The fuge has lots of Chaeto, some Gracilaria's and small amounts of others...lights on 24/7. Sand is full of pods, stars and worms of all kinds.We did some changes on the tank yesterday but nothing I would think would effect these corals. We added a different skimmer, added a VERY small whisper filter with one charcoal filter cartridge in it to the fuge and did a 5 gal water change which matched in temp and salinity. Fed BTA and inverts last night which I do every few days. We also anchored some frags and rocks with putty which is known reef safe. Water parameters this morning are; salinity with refractometer .026 Ammonia between .25 and 0, Nitrite 0, Nitrate 0, PH is a little low at 7.8 which I've been fighting to keep up and add 2 teaspoons of baking soda in water every day. I moved the mother colony of anthelia into a diff tank and could probably move xenia and Devil's hand if needed. See pics of Devil's hand below. Would appreciate any thoughts or advice on this problem. Thanks!!!
