Re: NANFA-L-- mollies and calcium

I have a ton of calcium in my molly tank.. it's also an apple snail
grow out tank, and I put about a cup a week of crushed shells in it. I
don't know what the hardness is, my test kit is a mid range and only
goes up to a few hundred ppm, but it's pretty hard. It's buffered
above 8ph while my tapwater is somewhere just above 7. Without sodium,
the mollies still have health issues.

I don't think that the issue there is what is comfortable for the
mollies, I think it is more the preventative properties of the salt.
Things like camelanus just can't survive in salty water.
