Thread: No chlorine

  1. Back To Top    #1

    No chlorine

    Hi,

    I am not sure what to do. I am a new pool owner and just recently switched it to a salt water pool (4 months ago). My pool reading is showing no chlorine. Here are my test results according to a local pool store.

    TC: 0
    FC:0
    pH:7.7
    Acid Demand:7
    Calcium: 500
    Stabilizer: 120
    Salt: 3400
    Phosphates: 1000

    They told me to add 4 cups of muriatic acid, wait 1 hour, add bottle of phosphate remover (32oz). Wait 24 hours then add 2 bags of shock.

    I have completed through the phosphate remover.

    Thanks in advance!

    Re: No chlorine

    Hello, and welcome to TFP!

    You don't need phosphate remover. That's the pool store's cash cow. As long as you have chlorine in the pool, you don't need to remove the phosphates.

    A salt water pool has to be "kick started" with bleach. The salt water system won't bring a pool with zero FC up to the proper range. We can get into the details later, but for now you essentially need 235 oz to bring your FC up to 12. At that point, the SWG SHOULD take over, as long as you don't have organics in the pool.

    Now to CYA (stabilizer). 120 is high. And I bet it's higher than 120. Anytime you get over 100, measuring CYA gets extremely inaccurate. Also, it's not uncommon for the pool stores to make errors when measuring CYA.

    DO NOT add more shock. Your CH of 500 and CYA of 120 (+) are already too high. All shock products either add CH (Calcium) or CYA (stabilizer), neither of which you want more of in your pool.

    My complete recommendation is this:
    1. Get 2 gallons of PLAIN bleach (not outdoor, scented, or low slosh) into the pool.
    2. Consider what you are going to do to lower CYA. You may have to drain 1/2 the pool to get into the 70-80 range, so keep that in mind as you make this decision. This will also assist you with lowering your CH level.
    3. Get a good test kit. We recommend the TF-100 from http://tftestkits.net You will have more reliable results when you do this yourself than what you will get from the pool store. Also you do not have to worry about them trying to "pool store" you with products you do not need.

    Again, welcome, and let's talk about how you want to fix the issue!

    Re: No chlorine

    Welcome to TFP.

    What size and type pool is it?

    Don't worry about the phosphates any more.

    Do you have any way of testing the water? You will need a good test kit but if you have something, we can help until you can get one ordered and delivered.

    The first thing you need to do is get some chlorine in there. Since I don't know what size your pool is I can't tell you how much bleach to add. but you can use the Pool Calculator to figure it out. I'd shoot for about 10 ppm FC.

    Re: No chlorine

    Thanks Robbie. I completely read right over that!

    Two large (121oz) of 8.25% bleach will raise your FC by 20 ppm. Not a bad place to start.

    Re: No chlorine

    Agreed. I just said enough to go to 12, but 20 won't hurt anything.

    Re: No chlorine

    Unfortunately, I had already added the phosphate remover before finding your website. I truly appreciate your help. I will be adding bleach as soon as possible. Is there a way to lower your CYA without draining half the pool? We live on a salt water canal and the EPA is funny about that.

    Re: No chlorine

    Your only option is draining and replacing water to lower the CYA.
    Or let it turn into a swamp over the winter and hope that the CYA gets converted to ammonia ... but that is not guaranteed to happen.

    Re: No chlorine

    Also, they calculated my pool size, but now I don't trust their expertise anymore. My pool is 12x29 ft and kidney shaped. It is also, 4 ft deep in the shallow end and 9 ft deep in the deep end. Am I right about the 13,000?

    Re: No chlorine

    13k seems about right to me, certainly close enough to start with and use for dose calculations.

    Re: No chlorine

    Tell the EPA you are draining salt water with no chlorine in it.

    Re: No chlorine

    After adding the chlorine, how soon should I see results?

    Re: No chlorine

    You should be able to see some FC in the water immediately, but wait about 15 to 30 minutes to test and see how much you have.

    Re: No chlorine

    Now my TC is 5 and FCC is 5. I have two little girls who are dying to swim. When can I let them in again? The pool is still cloudy and I want to wait until after this weekend to empty out the pool. Will that be ok?

    Re: No chlorine

    Can you see the bottom of the pool clearly? If so let them swim. Keep some chlorine in there.

    Yes, I can see the bottom and by adding chlorine, you mean bleach, right?!

    Yes, Liquid Chlorine=Bleach.

    They have different names at different strengths but they are a the same "liquid chlorine" with different amounts of water (and minor, unimportant differences)
