    Default DIFFERENCE IN 12% and 8.25

    Ok I am adhering to everything on this site, but one question I am buying 8.25 bleach from WM to bump and 12% from pool store. Now, WM for 3.00 is much cheaper than 12% pool store. My concern is will my pool really tell the difference? If not I'm WM bound for all chlorine needs.

    I only trust the k-2006 titration is better for me

    Same chemical, just different concentrations. The only 2 things that matter are 1) dosing appropriately based on the % and your size pool, and 2) price. To easily compare prices, $/oz./%. So if wm bleach is $3.25 and pool store is $5.00 and both are 1 gallon, 3.25/128/0.0825 = 30.78 cents per ounce of sodium hypochlorite and 5.00/128/0.12 = 32.55 cents per ounce of sodium hypochlorite. Walmart wins.

    but doesn't the higher % of chlorine give you more chlorine per gallon?

    Sure. You need to dose accordingly... I use poolcalculator.com. However converting to $/ounce allows you to compare apples-apples for price. In other words, you have to use more wm bleach but its cheaper to do so.
