I have a in ground plaster/gunite pool approx. 17,000 gal. The pool is less than a year old, and I think my CYA levels are already high. Is this possible? I use tri-chlor tablets, and I know they sluff CYA but I was under the impression that it would take years. I am currently in the 80-85 range as best I can tell with the TF-100. I have never added stabilizer other than what is in the tablets that I know of, so dont know where its coming from. I don't want to have to drain/fill my new pool, especially since it is finally getting to be the perfect time for using it. My current numbers are:
FC - 10
CC - 0
TC - 10
Ph - 7.2
T/A - 70
CH - 230
CYA - 75-85 best I can tell
Temp - 88
I know the FC is high, but I juiced up the chlorinator to get rid of a few little algae spots after I hit them with the brush. Guess I should stick with liquid bleach when I need to raise the chlorine a lot instead of using the chlorinator? Any help with this would be great. I guess my big qestion is; is it possible for CYA to get that high that fast?
Thanks,
Eric
