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

Well, most likely if it is like Kalkwasser, than it adds Alkalinity and Calcium back into the tank at about the same rate. If you are wanting to add just Calcium and not Alkalinity, then I would look at using the Calcium part of a 2 Part Supplement such as B-Ionic or even Randy Holmes-Farley's recipe.

I have a CA Reactor running and I just want to supplement it with some kalk and I have Seachem product already and thought if it was really the same I would try it out

According to the specs, it sounds like calcium chloride with Magnesium and Strontium added as well, so it's not like kalk.
