Raising Calcium level with cal-hypo

[duraleigh]

Tomcat,

That a good question and I sorta' think no one really knows the answer. I'm sure there is no drop dead absolute number in excess of which your pool will turn to limestone instead of water.

That would be similar to thinking that 12ppm of chlorine is perfectly safe but 12.5ppm will bleach your liner and cause you to grow extra appendages.

Your logic to monitor pH and Alk is probably key to high calcium management. You could lower your pool level in anticipation of the monsoons to get even more dilution over the winter but, if you do the math, it'll take a pretty big drainage to get you prepared for Cal Hypo all next Summer....probably 50% or more.
