I’m sorry I made a mistake in the calculations in my brain. Tried to clarify in first post just now. I forgot that there were two parts of salinity measuring. I made a mistake. Sorry againUnless OP changed the Salinity, this is completely bad and wrong information. Reef salinity is 35 ppt.Salinity is way to high. I suggest keeping you salinity at 1.024-1.027 ppt. Do you have livestock in the tank other than the peppermint? If you don't, do a water change and put barely any salt in to level the salinity. Peppermint shrimp is likely going to die, but it might survive. Do gradual water changes with low salinity to stabilize it and slowly decrease the salinity
