Not disagreeing with low salinity tanks, Ive seen them too, but it would explain the short time before the OP's sps all died. I can almost guarantee wherever he gets his corals from, the tanks there are not kept at 1.022; most lfs keep their tanks at the same salinity most reefers target: 1.025 (give or take a bit). the rapid jump to 1.022 is enough to kill a coral imo. I also have to aske how it was measured; hydrometer? refractometer? calibrated or not for either?
