Magnesium Dosing

[brandong]

I am not sure how much of this product I can add per day safely to bring up my magnesium levels. I am sitting at 970 PPM and want to get to 1300. Can someone help please.

its going to be about 380ml to take it up to NSW of 1350.
Do not add all at once, so add in 100ml per day for 3 days.

I would not add any until you triple check that reading and confirm it is also not a low salinity problem. I cannot see how mag gets that low except through no dosing or water changes for a long time in a tank dosing
Large amounts of calcium and alk.
