No major changes. CH was around 425 a month ago. It started around 275 after the fill, but the rise has slowed over the last 2 months. TA has been in 80-90 range for the last 2 months and has never been higher than 90. I added the borates around 2.5 months ago as well... I'm guessing on the borates since I find it hard to read the strips between 30-50... it was probably a little higher 2-3 weeks ago. So do I have something interesting going on here? I'm planning on putting in ~15 ppm of CYA tomorrow unless there are some other ideas. I did recently buy additional taylor CYA reagent from the pool store. Could there be an issue with the reagent? Today was the first time I used something other than what came with the TFT kit. The pH rise is beginning to be quite a pain as well. It wasn't this quick until the temp went up and I raised the SWG percentage.
FC has always been in the 3-6 range. The pool builder started the CYA at 100, but it came down to 80 after heavy rains in April.
