I have been using the same bucket of Kent for the 2 months my tank has been running. Now mind you I have no stonies in it that are using Ca, but assume my cleaners are all using some to build their shells and so is my coralline? My Ca has been between 500-520. I was kinda worried about it at first, being too high? But everyone seems happy.
