Hello, and thanks for any input. I am still learning this pool chemistry thing. My CYA is off the charts, what I want to know to avoid this in the future is what causes this? (commercial chlorine tabs?)
Ok, I tried Bio whatever to reduce CYA, worked somewhat, but did not work is the summary.
I will do a water exchange, while the calculator says remove 70%, that is not happening, I was going to do 20-30% for now.
Here is my latest test results, and all my results since acquiring my Taylor K-2006 have been uniform.
FC- .2 (raised daily, using liquid 10% it doesn't last long and requires 32+oz daily)
CYA- off the charts (black dot disappears with about 1/2" in tube)
My question is, when I do the water exchange what should I do to not mess up the water when adding all the new water?
Next question when filling from the tap, does anyone add some sort of RV type filter to somewhat treat the tap water? Or just adjust after adding?
Thanks so much
