This is my first year and first time pool owner. I have been testing my pool reguarly for the last few weeks, I missed out on the Calcium Hardness test and my plaster/gunnite pool(24700 gallons) is at 150 PPM. The rest of my #s are fine(CYA slightly lower at 20-30 ppm, but I am going to use tablets when I go on vacation in a few weeks).
As per the calculator for me to bring up my level from 150 to 250 ppm I need to dump about 23 lbs of the Calcium Chloride in. The pool school says I need to spread this on the deep end of the pool. That is a pretty significant quantity of this stuff and my children are using the pool everyday, should I do 4-5 lbs/day over the next few days to bring it up or can I just dump it all in 1 shot. Will it disolve that quickly or should I mix it in a bucket before pouring it in to make it quicker.
Thanks for all your help.
