So quite awhile back I tried the UPS only epsome or no ups whatever the article said and shrtly after all of my coral began to die. It may have been magnesium poisoning or something in the epsom salt. But here I am probably over a year now and still having trouble. I bought a gsp rock and being in my tank for less than a week killed it. It never opened so I put it into a 10 and it melted. The mishap killed gsp, Sinualria, Anthelia and palys. But now my Palys are trying to return. This is why I bought the gsp. I thought the coast was clear. There is a mushroom in the gsp rock that did not die though. I also tried a gsp frag a few montha ago and it never opened. So I'm not sure what kills gsp but not mushrooms. Maybe it would have eventually killed the mushroom but it did not. I have a 120 sump with chaeto. I run 1500 gph of mechanical filtration as the tank has Triggers, Groupers amd Eels. The tank is a 180. The fish have not ever died from this. I thought it was ok because Palys have appeared without being added after many months of the tank rock being bare. They are the same ones I had before.
