OK....I think the leathers should go, except for my big happy finger leather who looks fine.
The skimmer has only been down for a couple of days, and the corals have been cranky longer than that...it certainly isn't helping, but I don't think that was the cause of the problem.
I'm a little confused...I thought the leathers were the ones that produced substances that bothered the LPS
corals, not the other way around. In my tank, more of the LPSs are fine (the candy cane and frogspawn look great) and it's the leathers that are bothering each other, and the brain. Am I right, and/or is it certain LPSs that are more bothered by certain leathers?
