47 Pounds of Calcium Chloride

[Captain 776]

My pool is 2 yrs old, it has always been sparklingly clear and still is.
I did a full range of tests today and Pool Math advises 760 oz (47.5 Pounds)of Calcium Chloride. Does that sound right? Have any of you ever added that much to a pool?

FC-8
CC-.5
PH-7.4
TA-30
CH-100
CYA-0

Adding PH Up, Baking Soda, Cyanuric acid.......all no problem

Thanks,

Bruce

Yes, plenty of people have added that much or more. Your water is too aggressive right now and will dissolve calcium out of the grout. Use PoolMath to see what your CSI is. Make sure it stays between -0.3 and +0.3. More here, Pool School - Calcium Scaling

Raise your TA to 60 and CH to 250.

Excellent that you have reliable testing and good to hear that you're going to get your water balanced and grout protected. Sounds like a beautiful pool!
