My tank yesterday was doing fine.recently I started doing Dino X treatment in the tank and now most of my corals are shriveling up. is this normal. Water tested normal but salt was at 1.022 ppm
Salinity is a tad low... If it was me I would to a 50% water change straight away. Mix your new batch of saltwater to match your current salinity(1.022). Then after a day or two recheck salinity, then make another batch of saltwater at the new salinity and complete another 50% water change. As water evaporates top off with saltwater made at 1.025 until tank salinity comes up to 1.025. Check salinity frequently!
This will pull the medication out of the water that is likely irritating the coral while gently and slowly getting salinity back in line.
I've had success beating dino 3 times with tank black outs and plenty of flow. Never used any chemicals.
