Hello,
Thank you for this web site !! I bought a house a few months ago
and a pool came with it. I previously had only a jaccuzi, but
that made me confortable with chemical testing the pool.
In going with recommendations of different sources, this site,
other internet articles, I stopped using the tri-chlor tabs the previous owner used,
because CYA level is around 70 I think ( the dot is a hard test for me). I went with
Cal-Hypo powder instead. here's my latest readings using my DPD test kit:
FC - 4.0
CC - not sure, it only gets slightly darker with my DPD test
pH - 7.5
TA - 100
CH - 350
CYA - 70
My questions:
1) your FC recommendations are 3-7, but the tester tops out at 5,
and the pool store says keep it at 2-4. Why the difference of opinion?
2)Should I get - FAS-DPD test kit, or just shock with any CC darker tester color change?
3) Should I do a 50% drain and lower my CYA?
4) Should I be concerned about the CH, and does CalTreat work
I am thinking of using 12.5% liquid bleach when my cal-hypo runs out.
2 gallons for under $8 at my local Leslies.
5) Is Fresh n' Clear worth it?
I live in a sunny area of Nor Cal, ave summer is 90 degrees, but the pool is
partial shaded 50%, due to trees.
So far the pool is crystal clear.
Enough questions for now.
Thank You,
