I have been dripping kalk
mixed with white distilled vinegar as described here
For the past 4 days or so.
Results so far according to Red sea testers
has risen and from low to normal
Calcium has risen from 360 to 400
has risen from 8.2 to 8.4
All pretty much within 48 hours after beginning to drip the kalk
and seem to have leveled off.
I have been dripping enough to replace most if not all of my evaporation loss. My test for newly mixed change water when compared to my tank water since starting this process are nearly identical. Before my test for calcium and alk
from the tank water where always lower than newly mixed change water.
its a slam dunk. But then again thats what they told Presient Bush about the weapons of mass destruction and look where it got him.
