My pool guy used the pucks all summer and left me with a 125+ CYA. I got my own test kit around Christmas, Taylor K-2006C, and have been monitoring things myself. Through backwashing CYA is now down around 110 and with the rains I think this will be even lower before summer. I haven't added any chlorine in months, over the winter, until the other day. Free chlorine has gone down from 23 to 9, I put in bleach and raised it to 11.5 per the CYA chart. I took a sample just for fun to the local store and got hit with exactly the king of B.S. everyone says. I have a question about a couple of my readings and if I should put in any chemicals.
FC: 11.5, Store FC: 7.16 (I ran my test 5 times over two days, 11.5 all times)
CC: 0, Store CC: 0
pH: 7.5, Store pH: 8
TA: 70, Store: 62
Store Total Alkalinity (Adjusted): 26 (Will ask about this below)
CH: 180, Store: 147
CYA: 110 (guess since numbers only go to 100), Store: 108
Questions:
I know not to trust the store but why is their FC reading so much lower than mine?
My pH of 7.5 right in the acceptable limits. How long should I wait to take another pH reading?
My total alkalinity reading of 70 seems good but the store hit me with this Adjusted value of 26. They said it is because of my high CYA and want me to dump Alkalinity Plus into the water. Is this a real thing? I did some searches and came up empty.
My calcium hardness of 180 is under the recommended range of 200-500. Is it critical to add in some Calcium Plus for this? How long should I wait to check this reading again.
Thanks for the tips!
