Green Pool

[mbar]

You would need 9.3 gallons of bleach to raise your chlorine from .5 to 20 ppms in a 28,000 gallon pool with 6% bleach.

You have to put 28,000 in the "ppol size"
6 in the "Chlorine strength"
20 in the "ppm" increase"

click on calculate, and it will show how many gallons in the shaded area on the bottom.

Walmart used to sell a 5 way test kit. I am not familiar with any now - I used the one from Walmart a couple of years ago before I got "Ben's" kit. You can get any drop based kit for chlorine, do a search for "shot glass method" on this forum, and it will tell you how to dilute the test so it goes up passed five. Maybe someone will chime in here with some more ideas.
