Hi all, yesterday I placed a coral in my tank using nyos reef putty. the tank went cloudy and the skimmer stopped skimming. the two fish I have stopped swimming. My two snails tried to escape the tank! I couldn’t catch the fish without removing rocks which I thought would create more problems. All my corals were ok so I did a 50% water change. Today the fish are a bit more mobile one snail didn’t make it unfortunately and the skimmers still not skimming despite trying to dial it up. Any thoughts?
