Sorry for delay, had to take kid to dr. Alright I have a 60 gallon aquarium, it is open on top, I measure my salinity with a normal cheapo hydrometer, the tang and green bubble anemone were both new purchases from phenomanal equatics 50% off sale. Has been running for approx year and a half. Tang is now dead, anemone is opened up and fine. Guess he was just expelling some squid i fed last night. Thanks for everyones help, is my ph too off, should I add some pH buffer? I have also read about having a higher salinity for mixed reefs, but I buy my water all pre-made, should I just add a little extra during water changes?
