Full history. This summer completes the 10th season of this pool. I am the only owner this pool has ever seen. I have always maintained the pool following advice of trusted pool supply store - no pool maintenance services. I have always used 3" pucks until this last summer when I switched 1" pucks for a chlorine floater. And I use granulated chlorine for shock (sodium dichloro-s-triazinetrione dihydrate). My pool has been clean & clear over the years, though I experienced some problems with pH & clarity this year. I also have problems with calcium scale, I fear. The water today is crystal clear.
Having said all that, here are the numbers.
FC - 0 (I expected this - not worried)
pH - 7.2
TA - 110
CH - 475
CYA - 150+
CYA not most accurate read. I blocked out the black dot at the 1.8ml line on the small comparator tube.
I've reviewed the pool calculator & I understand the Chlorine & pH steps. TA, CH, & CYA numbers look really high. Advice & recommendations?
Thanks
