Re: DYING RED RAMS HORN SNAILS an enigma



Lee, you are right.  

I think the terminology could be tweaked. It's supposed to be calcium alkalinity, I think, rather than calcium hardness but the  second terms are used interchangeably many times even though they are not strictly the same. Dissolved calcium  or calcium content are also terms I hear used.
  
Your point is still right regardless of the word-quibble. Baking soda adds no calcium. It also dissolves very quickly, boosting the pH almost instantly, something very harmful to fish and possibly other aquatic life forms as well. Things like oyster shell, aragonite, limestone, and tufa rock( mostly calcium carbonate), are much better simply because they dissolve more slowly. To make a comparison, the world's fastest car would likely not be the "best" car to drive to work or to pick up the kids at soccer. Adding Kalkwasser and other calcium additives has to be done carefully and gradually, and they are useful additives because they add the right minerals to the water. It's not just getting the pH numbers right, but getting the mineral content right also.

But that would only raise the pH, and have no effect on Calcium hardness.
