I tested my Ph today and it was below 8.1. I dosed a few grains of PH buffer from Seachem directly into the tank, which turned out wasn't a good idea. One of my zoos colony closed off immediately. 2 of my shrooms
shrunk to a tiny size then from their mouths, tentacles things came out. My red shroom sucked those back up already but my other shroom has not. I should have missed the grains into freshwater first
stupid me. Would that stupid mistake do permanent damages on my corals?
