This is our 2nd summer with an inground pool. Last year it was balanced by the company that installed it, and all I had to do was shock it. It's 29,000 gallons w/ gunite. We have an automatic clorine tube with 3" tabs and a nature 2 system. Here are my readings from Saturday at our pool store:
CYA:119---Their test range is 30-200, so they say this is normal. I've read on your sight it's on the high end. They sold me stabilizer a few weeks ago because it wasn't in range, and we were using cal-hypo chlorine for the winter but I switched to diclor about a month ago. I've been reading about using liquid chlorine here.
TC: 0 I had not shocked in a week.
pH:7.4
TA: 109
Adj. TA: 73 ---For which they told me to use 12 lbs of sodium bicarbonate. 4 lbs every 3 hours. I've only done this once so far.
Total Hardness: 399---No distinction of calcium etc. For this, they sold me a sequestering agent, and I was told to use 47 ozs. I have done this.
What chemicals would you suggest. I have kids in the pool everyday, all day. I teach private swimming lessons.
Thanks for any advice.
