Now at Mag 1350, Cal 460, and KH 9.6

there would have been a water change and the magnesium would have been low in the salt mix , there isnt anything else in a reef system that uses magnesium besides the animals themselves and mg consumption is about %10 of calcium or about 1-2ppm per day.

good luck , always test your new salt and if need be bring your mg up
