Help- Acros on fast slide

SkinnyMcGinny · Oct 26, 2020

I've had about 10 to 15 acros (and about 50 different corals total) growing very successfully in a 285 gallon tank for 3-4 years now. I noticed tissue looking a little thin on one of the acros a few days ago. (I don't know all of the acro's names). Well, I'm in full meltdown now. It's now spread to three different tabling acro colonies, (one is a pink lemonade) and it's happening fast. I checked parameters and all seem normal. My all fluctuates between 7.7 and 8.0, and that's where it was last night and about an hour ago, but that is normal based on time of day for me. My question is, is there any way to stop this? A photo of vanishing acre area is attached.

Yikes! Something has changed. What are all your parameters? Start fragging and do some large volume water changes. Are they bleaching or is it RTN?

I think I found the problem... A heater failed in my mixing drum, leaked all over, lots of rust in mixing drum. So I'm cleaning the drum, doing water changes, adding carbon filters, and crossing fingers.
