I have a 26,000 gal in ground pool with chlorine and a Pentair heater.
I went to a pool store with my water sample. They said my copper was 3.5 and my heater exchanger must be bad so I need a new one. They also said getting the copper out
of the water will be expensive and suggested I could just drain the pool to about a foot deep and start over. The results from my water test was as following:
CYA 137, Tot. Chlorine 4.8, FC 3.5, pH < 6.6, Tot Alkalinity 0, Adj. Tot Alk. 0, Tot Hardness 40, Copper 3.5, Iron .2
My water color is nice and clear. They said I could add 8 quarts of Pool Magnet Plus, then Sparkle up and then Kleen It. I also needed 56 lbs of Total Alkalinity.
I figured I was better off draining the pool. I am wondering if that is correct. If I do drain the pool when I start over, what will I need to add when I start back up.
I purchased a new heater so I will not keep putting copper back in the pool. I usually used two bags of shock a week as that is what the pool builder instructed me to do when I had it built.
Thank you for any assistance.
