Reef Advantage Calcium vs Kalkwasser

[marinelife]

I have a bottle of Reef advantage and it says it is like Kalkwasser.
So is it the same?

I want to add a calcium supplement to aid my CA Reactor

Its just a calcium additive like calcium chloride. It adds calcium and NO alk. So if you find your ca low then its fine. If you find your alk low you'll need to add something else like baking soda.
