green pool: like black/green pool

[bazman]

i chlorine tested twice since i got home.
both times, the results were more ridiculous than below.
the last test i:
filled the container up to 10 ml
added two dippers of r870 (presuming dippers are the scoop piece at the end)
water turned and stayed bright pink.
i added r871. to return to colorless, i added 9 drops.
per the instructuions, that is 45ppm. is that possible?

fwiw, the CC was 45 also, as it took 9 drops to bring that test water to colorless)


in all i have added 11 x 1-75 gallons of 6% bleach since sunday.

Dipper looks like a little spoon. Flat end is the handle.

That would be 4.5 ppm and is very possible. 9 drops x .5 = 4.5 ppm FC, not 45 ppm

You mean it turned pink again after adding the third reagent and the second titration took aonther 9 drops to turn colorless? That would mean a LOT of CC, 4.5 ppm, and that you need to continue shocking the water. These readings are not unusual with a green pool.
However, if you added the 5 drops of the third reagent and the sample stayed colorless then the CC would be 0 ppm.

Why do you consider these results ridiculous?
After reading through your thread I believe that yoiu might not be doing the chlorine tests properly. I wounder if you would document the next time step by step exactly what you are doing so we can double check you. I have already found one error that I noted above and am not sure but might have spotted another one.
