So I've been reading through the forum on this issue and see a TON of threads about it. Nonetheless, I'll make another one on the issue with the question...
How long will it take via evaporation, kids splashing, automatic refill via fresh water to get CYA level down to 30-50ppm?
Background...I am in Southern California with summers up to 100 degrees and winter below zero (elevation 2500 feet). Pool was built last summer, non-salt pool, with a Rainbow In-Line Chlorinator with Clorox 3" Xtra Blue tabs in the chlorinator. No other chlorine other than a weekly shock of Clorox Shock XtraBlue. I have had zero issues visibly with the pool and up until a week ago, been using Aquachek test strips with all levels in the ideal range (after adjustments). This included a CYA level on the strip at 30-50 range. I had never seen it higher until....
Starting about a month ago, I had trouble maintaining a chlorine level of 3ppm using the in-line chlorinator, despite it being on the max setting. AFter much research, this could have been due to the Rainbow 320 plumbed on the bottom thread and the fact my VS pump wasn't at high enough RPM. Yesterday, I moved the plumbing to the top and increased my RPM throughout the 8-hour run time each day.
I also decided to get my levels tested at Leslie's for the first time 5 days ago, which showed:
FC-3
TC-3
ph-7.4
TA-57
CH-100
CYA-70
Iron-0
Copper-0
Phospahtes-1000
TDS-650
I also bought a Taylor K-2006 test kit and measured the last three days, which resulted in the following results:
FC-2.6
CC-.4
PH-7.2
TA-90
Calcium-170
CYA-120
What I find interesting is the CYA of Leslie's vs Taylor being so far apart despite being within 2 days of each other.
CONCLUSION
I am going to start buying liquid chlorine and only using the chlorinator as a maintenance thing if I got out of town. My question is, do I have to drain the pool or how long would it take to get my CYA down to "normal" levels via evaporation, splash out, etc.?
Thanks!
