What is your preferred kalkwasser??

[ReefGuy1234]

I'm getting into corals and have decided that kalkwasser would be a better opinion to maintain my tanks parameters. There are so many different brands of kalkwasser so I wanted to know what is the best/preferred kalkwasser to use?

Any food (FCC), water (WCC), pharma (USP) or ACS Reagent (AR) grade calcium oxide or hydroxide is suitable, IMO.

I show what those different grades mean here:
