Well I just did something really stupid I think. I was going to adjust my PH in a 75 gallon saltwater tank. I bought some proper PH 8.2. Well says it is safe. It takes 3 and a half packets to adjust my tank it says. Soon as I put the second packet in all hell broke loose. My big beautiful purple long tentacled anemone just shriveled up. Then my two brain corals shriveled up, and then my hammer coral. So I am kind of depressed right now. Seems like the only thing it didn't effect were the xenia, and the fish. Looks like everything else is pretty much shriveled up. Anyone had any experience like that. This just happened about 15 min ago, and I don't know what is going to happen.
