how much Calcium

I thought about doing that what you do. take the RO/DI water add so much magnesium? mix it for 24 hours
then you add Calcium I can't remember how much.

For IO salt this is what I do (I mix 40 gallon drums, but I will do the below assuming a 20 gallon container):

For 20 gallons of water:

-fill container with 20 gallons of RO/DI water
-start mixing with pump (will also heat water, so a big pump is good, then you don't need a heater!)
-add 27 tsp of magnesium, will bring IO salt from about 1200 to 1380 ppm
-mix till it is all dissolved
-add 4 tsp of calcium (Calcium Hydroxide Dihydrate [DOW's flake]), this brings up level for IO salt from about 360 to 430 ppm
-mix till it is all dissolved

-then add the salt to bring specific gravity up to about 1.024-1.026
-wait for at least a few hours.

DONE!
