Bens Bleach Calc???????????

MWSmith2's bleach calculator is a Windows only program -- no Linux, no MAC's, etc.

Sorry!

But you can program the bleach forumla into any spreadsheet:

FC = (1,000,000/PoolVol) * Concentration * BleachVol

FC is Free Chlorine added in ppm

1,000,000 is because we are computing Parts Per Milllion--ppm.

PoolVol is the number of gallons or liters in your pool

Concentration is the strength of your bleach as a decimal, not a percentage. So 5.25% is entered as .0525, and 12.5% is entered as .125

BleachVol is how much you are adding, in gallons or liters--it just has to be the same units as PoolVol.

So if you add 1 gallon of regular bleach to 10,000 gallons in a pool, the formula looks like:

FC = (1,000,000 / 10,000) * .0525 * 1

and therefore FC = 5.25ppm added.

This gives us a REALLY easy rule of thumb: 1 gallon of bleach added to 10,000 gallons will ALWAYS give us its concentration as ppm added.

So if you run the formula with 1 gallon of ultra, (6%), you'll get 6ppm, with 12.5%, you'll get 12.5ppm. And if you try it with a 3-quart bottle of Ultra, well you'll get 3/4 of 6ppm--4.5ppm. Very easy if you cannot get MWSmith2's calc because you have a Mac.

It doesn't compute all the other stuff Michael computes, but it does do bleach.

Where is the good Mr. Smith these days?
