I agree, I lost my meteor shower and my monti caps took a beating when my salinity creeped up to 1.029Ive acually ran a system with a sg of 1.028 for years and never had an issue either,my tank seemed to be doing alot better around the 1.026 to 1.028 range i could say the higher mag levels exploading coraline growth but once my sg went higher then that my cyphastreas would burn around the rims
