Headed out to get more acid to keep the pH at 7.0, but glad to see that the CC finally is in the 1 - 2 range. Thanks for the reminder about POPP Carl.

"So..his (Ben's) recommendation was to break it (the ammonia) down slowly with the lower doses of bleach, until you start getting CC readings of 1 or 2--at which time you can up the doseage and go ahead and get rid of it. So...stick with the 6 gallon dose for now."

This is the 2nd day that my CC was 2 or lower. Is it time to up the dosage of bleach?

Here're this evening's numbers:
FC 0.0
CC between 1.5 and 2.0
pH 7.4 (put in 30 oz dry acid)
TA 190

Thanks!

If you want to go to a 9 gallon dose, that would be OK.

If you can, use muriatic instead of dry acid. It's cheaper, stronger, and better for your pool. Of course it's more noxious to handle -- gloves, glasses & watch the fumes when you pour! But you're going to need to lower your alkalinity, so keep pushing the pH back down.

Thanks Ben - I'll up the dose to 9 gallons starting with this evening's dose.

Tonight the dosage increased to 9 gallons of 6% bleach - water is quite green, visibility about 20"
Ordered a couple 5 gal carboys from Uline and found a local cleaning supply that sells 12.5% bleach for $2.75/gal. so I can keep up the dosage until the water clears - it will seem like alchemy when it does!
