Help dosing Brightwell Magnesion-p

[gregzz4]

The amount of Mag that you mention for your 'total' dose is what you would add over a period of time
Without raising your Mag by 100ppm per day, decide how much you will add each day

You mention 62.4g
This will raise your Mag to your desired level, but you want to do it over time, without raising your level more than 100ppm/day

Test, dose, test .....
