I think the bigger concern would be the chloride part of the formula.
Althgouth it would be much more potential than Kalkwasser, you would
consistantly be adding chlorine in the form of a chloride to your system.
That just doesn't sound like good news to me at all. You would then need to
continually treat for chlorine rather than allow the hydroxide of standard
kalkwasser form more water molecules.

Perhaps someone with more extensive chemistry knowledge can add to this.

Does anyone use Calcuim Chloride for calcium supplimentation. Ive come
across some sold from a swimming pool outlet and am interetsed to hear
of anyone who has done the same. Its very potient. Unlike kalkwassser
(made from Calcuim hydroxide) a solution make from calcium chlroride
can be made a lot more potient (about 20 X that of kalk). The only
concern is what other chamicals that may be in the pool grade calcium
chloride.
