How much bleach for 7000 gallon pool?

[Budlight592]

Guess I need to try this BBB method and was curious how much bleach to add for a 7000 gallon pool. Or I guess ratio of gallon to ppm.

In 7K gallons, each 2 cups of 6% bleach you add will raise your FC by 1 ppm.

Thanks I have looked everywhere for dosage information for my size pool. Think I am going to take all the stuff out of the frog system and use BBB and pray for good results.

Great little app to do that.

I don't think you'll have to pray for good results. I can tell you from experience that if you follow the methods here and use the best guess chlorine chart here, you will have good results. I have not had one single problem this pool season and the only things that have been in my pool have been some trichlor for CYA and wal mart brand 6% bleach.

You have a PF of 19, so 1 gallon of PLAIN 6% bleach will add about 9 ppm of chlorine to your pool. A pound of undiluted dichor (55% available chlorine) will add about 10 ppm of chlorine and about 9 ppm of stabilizer.

Can't remember but what is the PF stand for. Also the frog system is all but gone now.

PF is a "pool factor"--a tool that Pooldoc uses to estimate effects on water with given amounts of chemicals...
