    Converting from Baquacil to Chlorine - Question

    I've stockpiled about 50 gallons of bleach, getting ready for the switch.
    After I vacuum out the initial debris after the cover was taken off, how much bleach do I start with?
    I ordered the TF-100 test kit last night, so I won't be able to get real results until it arrives.
    I have some test strips for the time being to test for baquacil and chlorine levels.
    I am ready to take pictures, i have been reading about all the colors that the water changes.

    Re: Converting from Baquacil to Chlorine - Question

    You want to raise the FC level to 15. Starting out your FC level should be zero, so that means adding 15 ppm of chlorine, which would be about 4 1/2 gallons of 6% bleach.

    Good Luck! (By the by we love to see pictures.)

    Re: Converting from Baquacil to Chlorine - Question

    Once you start, keep nailing it with bleach! <i.e. don't let the FC drop from 15>

    And lots of pics as Jason mentioned! 8)

    Conversion a Success ?

    I started adding bleach on Friday night(5/22), the pool turned colors fast.
    Yesterday(5/23) I nailed it all day with bleach, while I vacuumed and brushed.
    I could almost see the bottom in the deep end by late afternoon. I used 24 (1.42) gal.
    bottles of bleach.Back washed 8 times during the day. At 10:00 pm last night I tested, 36 drops of R-0871 and my 10ml sample was still pink.
    this morning(5/24) I tested at 6:00 am and again, 36 drops and still pink.
    Water is chrystal clear(amazing), clearest in years.
    Do I have too much bleach in the water? There is no sign of baqua-goo and the psi in the filter is the same as last night.

    Re: Converting from Baquacil to Chlorine - Question

    Yes, you are using too much chlorine. You don't want the FC level going above 15. Your test result showed FC at higher than 18.

    Since you didn't finish the test, you don't know what the FC level actually was, and so you don't know if you lost any FC overnight or not.

    You are doing very well, and you are clearly getting towards the end, but it would be good to get a clearer test result tonight to be sure you are completely done.

    Re: Converting from Baquacil to Chlorine - Question

    Held exactly 15 ppm of FC from 9:00 pm (5/24) to 6:00 am (5/25).
    Took a grand total of 31 (1.42 Gal.) jugs of bleach.
    But my CC reading this morning was 2.5. I added a one pound bag of shock (sodium dicholoro -s- triazinetrone)
    early in the am. A CC reading of 2.5 at noon, so I added another one pound bag of shock.
    Just took another reading, CC still at 2.5. What's up with that?

    Re: Converting from Baquacil to Chlorine - Question

    That would be remnants of GOO.

    Why the switch from liquid to powder?

    You must continue to shock until the CC is .5 or less! You're not done yet!

    Re: Converting from Baquacil to Chlorine - Question

    ......well, as Casey said, you're not done yet!

    Here's a step from Pool School on the Conversion:

    7. Your conversion is complete when ALL of the following are true:

    a. FC holds at 15ppm overnight - a loss of 1 ppm is generally considered acceptable.
    b. CC's are less than 0.5ppm.
    c. Your water is sparkling.
    .

    Then, you would change your filter media and then add CYA. So, keep shocking w/LC or bleach.
    TFP Moderator TF100 Test Kit TF100 TestKit YouTube Channel PoolMath
    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Re: Converting from Baquacil to Chlorine - Question

    I used powder because I read in the "how to" shock your pool that you should use another source of chlorine,
    but I just read it again and I don't have the swg or liquidator. my bad!

    Changing the filter media, what exactly does that mean with a DE Filter?

    It means you have to open it up and clean off all the grids, disposing of the DE inside the filter, and replacing it with fresh.

    Well that is good news, because a new grid is very expensive.
    Thanks for your patience.

    Re: Converting from baquacil to chlorine - need advice

    I've been holding FC at 15 ppm for 6 days and can't seem to get
    the CC below 1.0 ( 2 drops ). All the other tests are in range. The pool
    looks chrystal clear. I completely took apart the panels from my DE grid filter.
    No sign of goo anywhere (powerwashed them while it was apart). Tried blasting out the
    return plumbing by throttling valves - still no goo. Am I overlooking something?

    Re: Converting from Baquacil to Chlorine - Question

    Have you added CYA yet? It is time to add CYA when the FC level holds overnight and your have replaced the filter media. I believe you have done both of those things.

    The last little bit of CC can take an extra while to go away. To finish off, you want the pool to get as much sunlight as possible as the same time that the FC level is fairly high, and you can't do that without CYA.

    Re: Converting from Baquacil to Chlorine - Question

    Jep, what ideliver said. Keep FC around 15 during the day, which will be much simpler now that there is some CYA in the water, and a couple of sunny days and the CC level will be down.
