    I can't get my chlorine up. please help

    Hey guys, i bought a house with a pool and i'm an amatuer. I have read the shock method and tried to educate myself as best as i can. I dont have the test kit but i have a local pool store who tests for free and i have been using them. My pool is 30,000 gallons.
    SWG
    PH 7.7
    Alk 110
    calcium 200
    cya 75
    free chlorine .3
    total chlorine .5
    salt is at 2300 but i had to add calcium and they told me i cant add salt for 2 weeks after that. BTW the pool looks great

    My pool store seems to be at a loss as well. I put two tubs of Dy-chlor, 5 gallons of bleach, and some liquid chlorine super concentrate in over the last few weeks and my cholrine level never even gets to one.

    Last night i added the liquid chlorine. I dont have the brand handy but it was about 5x the concetrate of bleach if i remember correctly. I just dont see how i'm ever goign to get this pool around 20 when i can't even get it to 1. The pool store recommened i put 3 bags of 'refresh' and said it was a different kind of chlorine??? i take what they say with a grain of salt.

    so would your advice be to just keep pouring chlorine in?

    UGH ... get a kit and stop listening to that guy. Adding calcium has no affect on when you can add salt.

    Read Pool School. Get a kit and trust your own testing.

    You just need to keep adding bleach to reach shock level and then maintain it there following the shock process.

    So the water looks great, but you can not raise the FC level? What kind of chlorine test is the guy at the store using?

    Your pool store is full of it and doesn't know what they are talking about.

    Add your salt now if you are sure of your salt level. Abslutely no reason to wait. I hope they didn't sucker you into buying calcium increaser for a vinyl pool.

    Chlorine is consumed rapidly, and you can't rely on a pool store to test for you. They are wildly inaccurate, and you need to be testing several times a day.

    Your chlorine is rising, but is being consumed quickly. That is normal on opening. You need to test and add more an hour after you first dose in most cases.

    Re: I can't get my chlorine up. please help

    whodat? I'll tell you who that is it's a pool store VICTIM! You really need to be able to test on your own. You need to be able to calculate how much chlorine you need to add. You need to be able to determine what you need to add and what you don't. That is what this forum is all about. I was lucky and found it before my pool build. I've never been to a pool store and never shocked my pool.

    Please add your pool details and location as described HERE as it will help us help you.

    Is your pool vinyl or not? If it is plaster, then raising the CH may have been a good idea.

    Stop giving the pool store money. With that $500, you likely could have bought a kit, bought all the chemicals you need for the summer from a hardware store, and STILL had money left over for beer.

    Re: I can't get my chlorine up. please help

    ok. the pool store kept having me add stabalizer then shock. i think the stabalizer got my CYA number so high the pool wouldn't hold chlorine!?! Add that to the fact that i had no salt and they told me not to add any, maybe the SWG also couldnt generate salt?!?
    So started reading here and drained about 20% of my water as prescribed by the calculator and got my CYA number back down to 75.
    So now i ask you.
    It looks like my numbers are fine except my chlorine.
    I don't have any algae that i can see
    Should i shock my pool or just get my chlorine up to 5 and then my salt back to 3000?

    Re: I can't get my chlorine up. please help

    Since the FC keep dropping so fast, you need to go through the shock process:
    pool-school/shocking_your_pool

    Once you pass all 3 conditions to stop, then you can get the SWG going (although you can add the salt at any time).

    Problem is, the CYA from the store is not likely correct and you can not follow the shock process without one of the recommended test kits.

    If your CYA is truly 75ppm, then you need to maintain your FC at the shock level of 30ppm ... I doubt even your pool store can test that high ... thus you need the FAS-DPD test.

    I agree, testing on your own is the first step to gaining control of your pool

    You can keep adding a bleach to see when you actually get a FC reading.

    Since the CYA is high, your should not be losing a lot to the sun, so it is all fighting something in the water.

    rain has very little affect on shocking/chlorine levels unless alot of organic debris is falling into the pool.
