    Question about chlorinating while filling

    Hey guys and guys I have a question. The pool is finally standing and water going in. Woohoo. We have a well so it will take several days to fill it without killing the pump. It stormed really bad yesterday so I added about a quart of bleach (8.5) and about a 1/2 cup of dichlor. Skimmed the tree droppings this morning and checked chlorine and ph.

    Cl- 7
    Ph- 7.5

    Is it ok to keep chlorine around this level until the fill is complete and the pump started?

    I added some dichlor to put some cya in the water to protect the chlorine. Thanks!

    I don't see why not. What is your CYA ? What test kit are you using ?

    How much water was in the pool when you added the chemistry?

    Re: Question about chlorinating while filling

    I have maybe 1,000 gallons in it right now. I did not test the CYA this morning since I had 0 to start with.

    I am using the tf100 kit. I follow directions well!

    Here are the fill water numbers:

    Cl-0
    Ph-7.2
    TA-210
    CH-250

    I would shoot for a CYA of 30 ppm and keep FC level according to that. Remember CYA level wont show for about a week. I would also use just CYA in a sock in fromt of the return. Your TA is high also.

    When the water is high enough for the pump to be turned on I will put a sock of CYA in. I did not think the TA would hurt until I get the pool full. All I am hoping for right now is to keep algae at bay.

    Re: Question about chlorinating while filling

    Dose carefully and test carefully. a quart of bleach and 8oz of dichlor raised your FC by 60+ ppm and your CYA by 30 in 1000 gallons.

    That your FC is now only 7 ppm is a good thing and that you added some chlorine is a good thing, too, but use the poolcalculator next time and reduce that dosage.

    Never put chemicals in your pool unless you know the results beforehand.

    I know I made a booboo by just guessing. Did not even think of the calculator until about 2 hours after I had dosed the water. Oops! I will do better!

    No foul. It's part of the learning curve.

    Re: Question about chlorinating while filling

    I did the same thing last year with putting up my Intex last year. I started like you with filling from my well about 300 gallons a day. I would get in the pool with a half cup of bleach and walk around in a circle trickling the bleach in while the walking would circulate the water around. About 4 days of that and I gave up and paid the $250 for water. Still didn't have enough for the pump and needed 1 more day of fill from the well.

    The TA is just going to make the pH climb faster. It will come down as you lower the pH with acid. Once you get all of your other levels balanced you can focus on actively lowering it if you get bored.
