Info from Clorox on using their bleach for pools

When I diluted as in my last post, I dumped 1each – 182oz bottle of Clorox Ultra into a 6 gallon bucket. I then refilled the same bottle 3 times with pool water and combined these with the 7.2% bleach from the first step. To clarify --- that is 182 oz bleach and 546 oz water. This is a 1 to 3 solution ---- 4 parts total.

As for the dilution method for testing bleach I use a 1000 ml volumetric flask and a medical syringe used to perform the standard tuberculin “Tine” test. The syringe has a total capacity of 1 ml but is graduated in .01ml graduation intervals with major graduations at .1ml. Edit: The complete dilution method is only accurate to .1ml @20 deg C due to the accuracy of the volumetric flask ----- somehow I think that is "close enough".

Testing is done using the FAS-DPD method, using a 25ml sample size, again yielding accuracy within .2 ppm in a 10000 to 1 dilution.
If there is something wrong with the method please let me know. I have found the results to be repeatable with a 95% confidence level (in scientific terms [95 out of 100 tests]).

I am pretty anal with my testing methods.

Richard/FC,
Fair enough, I stand corrected.
