Wall Hammer is sick
We are new to the hobby and have been successful for 1 year. We have a wall hammer that has been sick for about 4 weeks and is getting worse. We have checked the water regularly and have taken a sample to our local fish store. (LFS response “never seen water this clean”) Water Changes every 2-3 weeks. All coral has been ok & some great. New acropora frags lost their color but they are growing & zoas do better when we give them more light. The wall hammer has been in the tank for 7-8 months. It has always appeared healthy but has not had much growth. When this started, a small crab appeared to be chewing on it and it closed in that section. We caught it early and it looked like a few heads closed and had not actually been chewed off. Crab was relocated, but closure continued on that side and a couple of weeks later closure started on the other side The coral beauty has left it alone but the tang has poked at it a few times in the area that appears dead. We don't feed the coral often, but tried to feed 3 times over the last week. We tried moving it to the top of the tank but no change. Also, tried moving it to a quarantine tank in case things were attacking when we aren't watching, but it got worse. It is currently in a low to moderate flow area.

This is my 17 year old son’s tank and I am the messenger. He says the temperature in the tank can fluctuate throughout the day by 1 degree. He knows alk is a bit low and does dose. Mag is a bit high and he does not dose that. Ph a bit low, but said he has read not to add a buffer.
