Ok...I may be losing it but here we go.

I want to bump my calcium in my Instant Ocean from 350 to 420. The calculator tells me to use .9g per gallon of dow flake.

I've figured out that there is .254g of calcium in .9g of calcium chloride. What is the math that shows this will add 70ppm per gallon??

I only ask because I have tried this and it didnt seem to raise the calcium like I thought it should.?? thanks
