Well my zoas that I got a while back have been doing great since I got them. Never a problem. On Fri. I went and got a frog spawn and a trumpet coral from Hung. Since then ALL of my zoas look shriveled up and the bases look thined out. Everything else in the tank seems to be doing fine. My fish are great. My leathers are perfect, my xenia are alright, shrooms perfect. I thought it might be a water problem so I checked the water and params seem good. My temp is 76, salinity .24, nitrates 0, nitrites 0, ammonia 0, Ph 8.2, Alk 3.5. Just in case, I did a 13 gallon water change anyway. And when I woke up this morning they were worse. I thought it could be that they were getting stung, but that cant be it because I got zoos all over in different spots of my tank and they are ALL doing the same thing. Any ideas. This is frusterating.
