    Cyanuric Acid

    Let me start off by saying to "tfp", the info is so helpful to all of us so thank you very much !
    I am wanting my chlorine to last longer and heard about the acid ? Should i go with the "hth" brand when getting cyanuric acid or some other brand? Thank you in advance.

    New pool owner so i don't know any of the logistics of my pool yet. working on it though

    Welcome to TFP!

    Cyanuric acid is pretty much the same regardless of who sells it. You do need to watch out for the rare versions that only contain 50% cyanuric acid. And the liquid form is more than twice as expensive as the solid. But other than that it is essentially all the same.

    Re: Cyanuric Acid

    Do you have current test results? What have you been using to add chlorine to your pool?

    We just want to be sure that the CYA is your problem and not something else going on.

    I agree. It would be a shame to add CYA if you already have plenty, as you can't adjust it in the other direction. Too much CYA creates a whole new set of problems. Chlorine is possibly getting used up by organics in the water.

    Re: Cyanuric Acid

    THANK YOU FOR YOUR RESPONSES.
    I TEST EVERY 2-3 DAYS AND MY CHLORINE IS GOOD. I HAVE FOUND, UNLESS WE HAVE A SWIM PARTY, THAT A RED "SOLO" CUP FULL OF DICHLOR WHEN THE LEVELS GET LOW (NOT COMPLETELY GONE ) PUTS IT BACK INTO THE GOOD RANGE. I THINK THAT IS
    PROBABLY EVERY TIME I CHECK IT, I DO THAT. SO ADDING A CUP FULL EVERY 2-3 DAYS.

    NOW I DO LIVE IN AZ, WHICH I'VE READ IS A KILLER ON THE CHLORINE. I WAS JUST WONDERING IF THAT OFTEN WAS NORMAL, CUZ THAT IS MY NORMAL AND WAS WONDERING IF IT SHOULD LAST LONGER ?
    WHAT DO YOU THINK OF THE TAYLOR K 2005 ?

    Re: Cyanuric Acid

    If you have been consistently using dichlor, you probably already have a boatload of CYA. Have you ever tested for it with your K-2005?

    Re: Cyanuric Acid

    <<Please do not use all caps. It is considered shouting.>>

    The K-2005 test kit is incomplete for the test kits suggested on here. It does not contain the FAS-DPD chlorine test. You can order that individually from http://www.tftestkits.net. If you haven't already purchased it, the K-2006 or the TF-100 is a much better choice.

    Since you have been using di-chlor, you already have stabilizer in your pool. You'll certainly want to figure out your CYA level before you add anymore.

    Re: Cyanuric Acid

    We do not trust statements that are too subjective like ... "my chlorine is good"

    I am glad I asked about what you use for chlorine as that dichlor likely has your CYA quite high already and more would only hurt you.

    I suggest you read through Pool School a few times (button at upper right) and hopefully realize that your current pool maintenance procedure is NOT going to work for very long. You need to learn about your pool's chemistry and then take control ... adding the FAS-DPD test will certainly help that.

    Now, post up a FULL set of test results using your K2005, so we can see what kind of shape you are really in. See this for more info on the tests:

    I don't know what you do for a living, but I hope you don't deal with customers on how to maintain their pools ! You are very RUDE, and if you guys are worried about a guy typing in CAPS, but allow a fellow " contributor " to talk to people like this, I can take my ?'s somewhere else ! I appreciate advice, since it is obvious that I am no chemist ! But to be told, " WE DON"T TRUST STATEMENTS ", " NOW " " HOPEFULLY REALIZE ", " YOU NEED TO LEARN ", well isn't that obvious that I need to learn ??????????????????????? That's why I am here, isn't it ??? Mr. Lion, I hope you can understand where I am coming from, and to the others that weren't RUDE either, I apologize !!!!! But no-one that is trying to learn something, needs to be treated like this ?? That is why I thought this forum was created and for ???


    If I could possibly get my ?'s answered when I get back to the rest of you, I sure would appreciate it !!!
    I don't have a K-2005, I have a DPD test kit from Leslies Pool Supply, but have taken into account the responses and am going to decide between the TF-100 or the K-2006. Thanks again for the responses and I will get back with you when I get a full realm of results.

    PLEASE DON'T RESPOND AGAIN jblizzle to anything that I post in here, due to the fact I WOULD never take any of your advice !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! But it is a free country, so do as you please.
