Auto watertop off with reef advantage calcium

[Silver]

I normally use Kalkwasser with my auto water top off system. This is a closed water system that I add my Kalkwasser to. Then when evaporates adds top off water and kalk to tank.
The problem when I made my last order at marine depot I thought I bought a bottle of Kalkwasser . BUT instead I got a bottle of (seachem) Reef advantage calcium.
Can I use this with the top system I have?
Do I use the same amount of powdered (AC), that I used of the Kalkwasser ?

Need help soon to keep my Kalk levels up.

Thanks
Jeff

The Reef Advantage Calcium will boost calcium only, and will not do anything for alkalinity.
