I dont know if this has happened to anyone else. But let me start the story I started dosing my tank with AB+ yesterday, After watching several videos showing how, and talking to several people who have used it, I went out bought some AB+. followed the dosing amount and how to dose to a T and did a dose. The reason why I purchased it is to help some of my coral that I was given that had STN that I have been recovering. Upon dosing my tank with AB+ I noticed by Brain coral, candy cane coral, and my duncan coral retracted entirely into their skeletons and released a thick defensive mucus, that is when I started to get very concerned, I asked my friend who recommended me to get AB+ he said that on his corals they release a mucus net to help capture more every time he feeds. So I trusted his word and went on with it. I woke up this morning, my corals were still retracted and covered in a thick mucus, had me worried but I had to go to work so I couldn't do anything at the time. I get back from work and check up on my tank. my corals are still retracted into their skeletons . a lot of the tissue is gone, and a concerningly large amount of the skeleton is all that is left over. I will now be throwing away the rest of my AB+. And will never touch another product from RedSea again. If anyone has also experienced this. or something similar, please let me know. Seeing as my brain coral is now dying from the very thing that was supposed to help it. Aside from keeping params stable? what else can I do to help my poor brain coral recover faster?
