I'm a newbie to both TFP and pool ownership. TFP has been fantastic for getting us up to speed on the ins and outs of pool chemistry - THANKS!! We just filled our brand new pool (16K in ground, SWG) two weeks ago and put salt in early this week. For the first week I was running OTO Chlorine, pH, and TA with the kit supplied by the PB. TA started out at 110 so I spent a few days reducing TA by the standard 'reduce pH/aerate' method. This morning the TA was down to 70 - score one for TFP...
My TF-100 kit arrived today, so now I can do better numbers (as a former chemist, I'm all for good numbers):
T 79 deg.
pH 7.5 (this has been going up and down as I've been lowering CH)
FC 5.5 (I got a little frisky with the chlorinator as the pump was running continuously during TA reduction)
CYA 60-70 ( I added for 80 ppm three days ago, so this may still go up)
salt 3700 (reading on the SWG unit)
The water looks and feels great, but I'm concerned about the high CC level (the test result is repeatable). Is this normal for a new pool, or is this indicating some problem? Will CC go down as things stabilize?
I'm also wondering if I need to worry about the CH level, although since they had to pound through limestone for 3 days digging my hole, I'm not surprised. Can I figure that normal rain dilution will eventually take that down to more normal level? Dilution is my long-range plan for getting the salt down a little as well.
Thanks for all of your help to this point and into the future!
