kalk idea (has anyone experemented with this)

Has anyone tried the following or comment on the idea:


- dosing Kalk mixed with existing sal****er rather than freshwater?
(ie take a litre out and drip it back in over time)
(for maybe those who can't evaporate enough water)


- using a long cylinder vertically mounted inside a a deep sump with
kalk powder in the bottom and a very small amount of circulation
running through the top of the cylinder.
