green pool: like black/green pool

Always better to add things gradually rather than a huge dose all at once and overshoot your target. 8 lbs. of Borax at one time is a lot. We'll see what your pH reading is in the morning, but in the future, I would advise against adding so much at once.

It is fine to add bleach and Borax at the same time. I do it all the time with no problem.

Not sure about the "white spray." Did it start before or after the Borax addition?

Repost in the morning with new numbers and tell us how the water looks. The more times per day that you can add enough bleach to get back up to shock level, the better. There is no such thing as testing and dosing with bleach too often. Glad it is looking better.

12 ppm is the level of FC (Free Chlorine) that your shooting for by adding bleach.

The objective is to get your FC to 12ppm and keep it there until you have zero CC and you don't loose anymore than 1ppm of FC overnight (Dusk till Dawn/before the sun hits the water).

Like Watermom said, there's no limit on the number of times you can test and dose to keep your level at 12ppm.

my wife just tested the ph and chlorine.
the ph is now at 8
free chlorine is now at 8,
combined chlroin ia now at 16.
after the test, she added two bottles (3gal).

I doubt that the CC is 16. If it is, you have a MAJOR PROBLEM! :eek:;)

Try those chlorine tests again.

Yeah, you could probably walk on that water--but I'd wear boots to do it!:p

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

i thought the results ridiculous because of my error in the calcs.
i did add the third reagent and the second titration took another 9 drops to turn colorless.
therefore the results seem to be getting where they need to be. slowly,
i will shock once more now. i will test again in an hour to check the chlorine level.

i tested last night an hour after i added 2 * 1.42gl * 6% bleach (~10:30pm)
the FC was 20.
this morning at 6 am the FC was 8.
i added 1 * 1.42gl * 6% bleach before catching my train
my wife added 1 * 1.42gl * 6% bleach ~10am.
she will not be testing, so the next test results i will have will be this evening.

sounds like you are on the right track. Just remember, patience and persistence!
