Ok added 3 additional boxes of Borax to raise the PH .They love me at Walmart

Finally today have success on PH as am at 7.2 --------------YES

Went back to same pool store today to test and they provided the readings on left with mine on right using the Walmart kit
CYA 70 (why did they get 110 yesterday?) I am out of chemical for this but I have been 50-60 . Assume this will impact what you tell me to do ?

Total Chlorine 0 Me 1 My kit only does Total .Will order Taylor in morning
Free Chlorine 0
PH 7.1 7.2 Me
Total Alkalinity 191 210 me
Total Hardness 229 210 me

They also said phosphates at 2500 and wanted to sell me phos out

My water is sparkling and 82F -never this way on Memorial Day in Pa

I added no bleach today - so GROUP what now as still cannot get a chlorine reading?
Another nice day on tap Memorial Day .
I tried to get a second pool store reading which is 11 miles away but closed .Nobody open now until Tuesday

Looking for advise
