Kalkwasser

[Crabs McJones]

Looking for information from anyone who uses Kalkwasser. I picked up a jug from Dr. Foster and Smith when I went on the Liveaquaria facility tour. It was on the clearance table for 4 bucks. So I figured I'd give it a try. My question to the experts is, when you mix up your saltwater to do a weekly water change, do you dose Kalkwasser into the mix or just solely into your RO/DI top off reservoir?
Any help is appreciated.

Thanks!

No, there's never a need to dose limewater into new salt water. It typically has plenty of calcium and alkalinity, and adding more this way will just cause precipitation.

This has more on what exactly it is:
