Off the charts chlorine question

[JazzMan2010]

Last saturday my polaris auto clear salt light came on so i checked and needed to raise salt levels. On that same day i also put on my solar cover and have left in on. That day i had a CYA of 80, PH of 7.4, and FC of 6. I left the autoclear on 8 hour run time for the past few days. A mistake because we haven't used the pool. too long a time. However, i just checked and i can't even get my Taylor Complete FAS-DPD K-2006 test to turn from red to clear. I went up to 40 ppm and then got tired of testing. Is it possible that my SWG created that much chlorine in so few days. I understand the cover helps the chlorine from being dissipated and my CYA is at a good level too. I tested it twice with 2 different dpd powders cause i have an extra. It just doesn't seem possible. Anyway, this evening i took of the cover so it could burn off some tommorow and had some chlorine neutralizer to try and drop it some. Anyone have anything similar ever happen?

I figured out my problem. It was my brain. I used the wrong reagent. I guess my wife is right i am losing my mind.

I did the same thing (twice) about a month ago. I was really scratching my head for a few days!

Anytime I get suspicious readings, that are really over-the-top, I double check and/or replace my reagents.

LOL – I bet that’s why my TA and CH tests indicate my pool water is concrete.

Thanks for posting this JazzMan (take my blues away.....)

I also have that basic question. Is it possible to generate too much chlorine with a SWCG?
