To raise Ca and Alk together try a little Kalk, use the calculator to figure out how much to add to your top off water.

Enter your present Ca and Alk readings, enter your target and select the product you want to use. I did it, I wanted to raise my Ca and Alk, to use ESV I would have had to use half the bottle of each. The target I wanted indicated I should add 5 litres of saturated limewater for the Ca and 2 liters for the Alk. I added the 2 and then a bit of the ESV a couple days later and Alk and Ca are great. Ca is 425 and Alk is 9dKH
