Not so, As stated from Hawley's Condensed Chemical Dictionary.
'All forms soluble in water and alcohol, water solution is neutral or
I make a 50% solution of CaCl2.2H2O (fw 147.02), for a Ca conc.
of 136,300 mg/L. From there I add what I need, which is hardly ever
over 3 or 4 ml for a 55L water column (only 1ml for 25% water
changes). I keep my Ca level around 30 mg/L. It does nothing to
my pH values. For those worried about the chloride, for every 10
mg/L of Ca, you get 18 mg/L chloride, which I feel is pretty
negligable. It's never caused me any problems. Hope that helps.
