Need to help add 25-50 lbs of calcium chloride to a neglected plaster pool.
Questions so far:
1) Do I pour the calcium chloride or the pool water in the bucket first? (if doing multiple buckets, need to dry after each if calcium first?)
2) If using a 5 gallon bucket, is it okay to expect 10 pounds of calcium chloride and 4 gallons of pool water or do I need to do less at a time?
3) mix with something other than your own hand and arm - seconds or minutes? until no powder sitting on bottom? until even cloudiness?
4) Distribute/pour back in - in front of return, deep end, around perimeter?
5) Using PoolMath I have a good estimate how much I'll need, but since the calculated gallons of the pool are best guess, I'd like to sneak up on target CH. How long to wait between testings given excellent circulation?
6) How long does the pump need to run after last addition is complete? Normal addition time of 15-30, 2 hours, 24 hours?
7) I have a few spots where the plaster has de-laminated and flaked off, exposing sub-surface/gunite whatever. I've read about calcium sticking to bottom when not added correctly. Thoughts on intentionally adding it incorrectly to these flaked off areas in an attempt to make a cosmetic calcium patch? Would it just come off during normal brushings?
8) PH was 7.5 at last check before FC was sent over 10, advise dropping to 7.2 with MA before CH addition to potentially reduce clouding?
Thank you!
