<< I see what you mean but is there any data about how much of the CaCl there
needs to be to allow salt water fish to live in CaCl instead of NaCl
solution?
I'm betting it doesn't need to be 1/1.

I think every species may have a different preferred concentration and
tolerance. Sea water analyzes as follows:
Element ppm
Sodium 10,800
Chlorine 19,400
Magnesium 1,290
Sulfur 904
Potassium 392
Calcium 411
Bromine 67.3
So that indicates that a much higher concentration of sodium is normal.
Substituting calcium may not be OK for all species.
