CYA 0-10

[Dba1047]

FC 4
CC 0
Ph 7.5
TA 60
Water Temp 84
12x24 above ground / heated
Ok - yes I went away for 10 days- my youngest
Added chlorine and tested levels - first time for her so we stuck to chlorine and ph while I was away -
Pool is crystal clear .
I forgot to log CYA last time I tested July 8th but on june 16 it was 50 .
We ve had extremely hot humid sunny weather for weeks -
And hard Heavy rains Where I literally opened up to waste and dumped water for 30 minutes to keep my above ground pool from seriously over flowing or collapsing
could the rain ,heat and seriously dumping water 5 ? Times over past 3-4 weeks remove/ dissipate/ degrade the CYA from 50 to 0?
Of course I gave a friend if one of my kids my huge bucket of pucks ( cause I m a believer !!)
ordered stabilizer - will add Friday but what am I missing ? Other than sigh - testing CYA as religiously as I test everything else ?
Oh and TA has been going down too
Thanks as always !!

Yes.

Add 40 ppm of stabilizer.

Dilution affects CYA greatly. I calculated you have about 9,000 gal pool If you drained 50% , plus rain, etc. then CYA could have lowered by 50%. For every foot of water equals 2,100 gals which is 23% of your pool volume. Hope this helps.
