Howdy folks!
Our pool was installed last summer and I thought it was fine per the pool store. We got all of the numbers where they were supposed to be. Water is crystal clear with an occasional tinge of green here and there but not out of hand.
Then I found this site! I started paying more attention to the fact that each pool test evaluation had cya at 100ppm and listed as OK. My test strips seemed to indicate it was getting higher (tri-chlor tablets). I asked the pool store guy why and he told me that was the highest value they could type into the program. Hmmmm???
Last night I took a normal sample and a 50% diluted sample to be tested. The guy told me the actual test result indicated 130ppm, and the 50/50 diluted sample verified that at about 65ppm.
Here are the numbers from their printout as of last night:
Free chlorine: 3 ppm
Total chlorine: 3 ppm
Combined chlorine: 0 ppm
pH: 7.6
Hardness: 250 ppm
Alkalinity: 100 ppm
CYA: 130 ppm
Total dissolved Solids: 1000 ppm
From what I am reading on this site, partial draining is in order. I am not sure how far to go yet as I have noticed on this site that some folks run the CYA a bit higher in these extremely hot southern conditions. Comments?
By the way, the TF-100 kit was ordered yesterday, and Walmart seems to be the best source of liquid chlorine.
Thanks in advance,
