Does anyone use the Two part solution

I just went ahead and ordered 4 gallons of it online. I will shop around when I get close to running out to make the calcium. I actually just found a brand new bottle of Seachem Calcium I guess it might be different if I used that in conjunction with the ALK. right or wrong?

You can use it, you just need to plug the numbers into the calculator for how much.
