What would happen if someone used calcium supplements intended for human
consumption to dose for calcium. I can envision Caltrate tablets slowly
releasing Ca++ into the water, but I guess someone would have already
started doing this if it were possible. I guess Ca++ has to be in the right
form. Any opinions on the subject?

Why would you do it ?
Would you want to save money ? Kill fish ? Other reason ?
