Chlorine and pH problems following missing stabilizer

[Cstaines]

"Store#2 had us put in 10# of granular dichlor chlorine (and check every 4 hours...if FC dropped below 5 ppm add another dose)...keep going until at 5 ppm for 24 hours without treatment. 25lbs sold for $99 and we used almost 3 before we lost hope...did nothing...money gone and CYA now sky high. We were desperate to get this cleared up...graduation party in three weeks, so we got sucked right in."


To answer the dichlor question:

Yes...as instructed by the pool store. They wanted us to keep going too...called it "chlorine demand."
The level would go to shock level...but the longest we could maintain 5ppm or higher was about 7 1/2 hours. It was Carribean Blue Chlorine Guard Granular Shock. They told us they are seeing an increasing number of pools with this problem.

I will send all numbers after lunchtime today.
