Hello, all of you inexplicably friendly folks.
I work in a pool store and had a gentleman come in at closing time tonight. He started a stain removal treatment on Friday afternoon. I didn't sell him the chems (his pool store was closed) but he is sure that the stain removal product was 100% ascorbic acid. Not sure what the active ingredient in the sequestering agent is.
Anyway, they didn't give him any instructions except to dump the acid in, followed immediately (as in 60 seconds) by the sequestering agent. He used all 4 lbs of acid in a 30k pool (doh!). The stains came up - but today his water clouded severely and his cell started flashing CHECK SALT and stopped producing chlorine. His cell reads 2600ppm, my meter at work read 3500ppm. The meter is calibrated correctly.
FC 0
TC 0
PH 7.8
TA 140
CH 80
CYA 30
salt 3500ppm
I instructed him to lower his PH to 7.2 and told him how much muriatic acid to use. He is bringing the cell in tomorrow morning at opening time so that I can test it for him.
Is there an issue with SWG's and the ascorbic acid treatment that is causing his cell to think he is low on salt?
If there *is* something wrong with the cell and it needs to be replaced, should he start introducing chlorine with dichlor or tablets? (his cya is a little low anyway - I can't really tell the guy to use bleach, but I will if either of the others will cause an issue)
Thanks if you take the time! And yes, I know that his water needs some tweaking, but I can give him that advice after the current issue is resolved.
(PS: Don't hate me, hate the system!)
