    Chlorine questions

    I just changed my 10,000 gallon above ground to salt water. It's gotten pretty hazy. I've put numerous chlorine tabs in the filter, shocked, but on my test strips, it still shows no chlorine levels. Am I using the wrong test strips? Is it a different kind of chlorine that the system produces?

    Welcome to TFP!

    Chlorine is chlorine, whether it is from tabs, the SWCG or a bleach bottle.

    Generally the water getting cloudy is the first sign that something is starting to grow,in the water, algae.

    Test strips are generally worthless for testing. You need a quality, accurate test kit to be able to follow our teachings. I recommend the TF100 at TFTestkits.net


    To follow our pool care recommendations you need a kit with the FAS-DPD chlorine test which most kits do not have. That test is generally not available locally.

    Get the TF100 from TFTestkits.net.

    And balance your water according to this, Pool School - Water Balance for SWGs

    The SwG Water Balance article will come into effect after you get your pool clear. Don't add any CYA until after it is clear.

    Yes, correct. If you have algae or don't pass the Overnight FC Loss Test (OCLT) then you will need to SLAM - Shock Level And Maintain your pool first to clear the algae and then resume normal pool maintenance.
