    No chlorine

    Opened the pool about a month ago but went away for a couple of weeks.
    I purchased the test kit. Just ran the two chlorine tests...the one in the blue box (Water was colorless) and the one in the "chlorine only" cylinder, did not get a pink color.
    So I'm assuming I do not have any chlorine in the pool, same goes for free chlorine.

    My SWG is at 30%.

    Any suggestions/help much appreciated!

    Re: No chlorine

    First, just want to cover your test kit details. The chlorine test in the blue box is called an OTO test, it measures total chlorine which is FC+CC. If it was colorless then you have neither. The other one is an FAS-DPD test, it measures FC, then you add the 5 drops of R-0003 and if it turns pink you have CC and can measure that. Just wanted to make sure you have the right understanding of the tests.

    Ok, so you have no chlorine, which is a problem. Have you measured your CYA level? If it is low then you might be losing FC to the sun. Either way you will want to get some chlorine in there right away so adding liquid chlorine to supplement your SWG will get your level up immediately.

    How does your water look?

    Thanks for the quick reply!

    Yes those are the tests.
    Water looks clear. Will check CYA level tomorrow.

    So just add generic store brand liquid bleach? In skimmer or throughout pool? How much?

    Thanks again!

    Add it near a return, and then brush it around a bit with your brush. Store brand liquid bleach is great as long as it's unscented and is not "splashless".

    Re: No chlorine

    You can do them at the same time. Add bleach, then get sock full of CYA hanging in front of a return.

    edit: While you are waiting for the sock to dissolve you could fill out your signature

    Re: No chlorine

    Ok, bleach has been added, as well as the conditioner. When should I retest again?

    And Robbie thank you for clarifying about the conditioner not going in the skimmer,
    I know I read to do that somewhere and that's where I originally put it.

    Also not sure why my signature is not showing up, it's filled out. Is there a reason it's not visible to people??

    Thanks everyone, this really is a great site! Very helpful and informAtive

    Re: No chlorine

    Need to check the Show Sig box below the text box. Once checked it will stay checked.

    Here is a sheet showing how to add chemicals, Pool School - Recommended Pool Chemicals

    Test FC after 15 minutes. Test CYA 24 hours after it is dissolved from the sock.
