How Much Bleach According to the Ben's Best Guide Chart?

[Pappy]

What is the concentration of the bleach? And the volume of the pool? I pour bleach through the skimmer with the pump running.

I purchase the bleach at Dollar Tree - Home Store Bleach. It does not state on the bottle but I would surmise it is 6% sodium hypochlorite. My pool is 20 x 44 - 30,000 to 35,000 gallons. I have used Clorox Concentrate a couple years ago and my pool started sudzing up. Someone on the forum told me that Clorox Concentrate should not do that but the Dollar Tree is the only place I can find regular bleach.

The way you calculate FC added is by the following formula:
(1,000,000/PV)*Conc*Amt= FC

PV= Pool Volume
Conc= Concentration of bleach as a decimal, so 6% is .06, 8.25% is .0825
Amt= Amount of bleach added in gallons--I usually use 1

To convert to odd amounts set Amt to 1, then divide by 128 (ounces), then multiply by the odd number of ounces.
