old basic bleach calculator

[CarlD]

I do it manually one of two ways:

Formal:

(1,000,000/pool gallons) * bleach concentration * Gallons of bleach = FC added to pool
Bleach concentration--if it's 6% bleach use .06, if 12.5%, use .125, if 5.25%, use .0525, etc.

If you use liters then use liters in BOTH places as Pool Liters and Liters of Bleach and it works the same.

Informal:
Or use the simple Rule of Thumb:

1 gallon adds exactly its percentage t0 10,000 gallons of water.

So... 1 gallon of 6% adds 6ppm to 10,000 gallons.

If you have 20,000 gallons, then 1 gallon of 6% only adds 3 ppm of FC.

1 gallon of 12.5% adds 12.5ppm to 10,000 gallons.

3 quarts of 6% adds only 4.5ppm to 10,000 gallons.

Adjust accordingly, but I can usually do it in my head this way.

Here's the BleachCalc link directly:

Don't forget that you can also use The Pool Calculator either online or saved to your computer offline or as an iPhone application (you pay for the latter).

The link Richard gave was to a post in archive section, which is only accessible to mods and "lifetimes". Most of the posts there are throwaways, but they are there so they can be checked first -- like this one.

That post is probably a throwaway now that Richard has put links here.

Deleting all the "I can't see it" comments.
