    Trying to clean my new green pool

    I'm in a similar situation pool wise, but don't know if I should start a new thread or continue my question here?
    Always start your own thread. It prevents hijacking Butterfly
    First, I'm new and ignorant to the ways of pools. I too have a high Cya number (Leslie's pool supply tested the water and it was 100+) so I assume continuing to try and shock or add chlorine at this point is meaningless. I stumbled onto TFS yesterday and I've learned a ton already...such as the Leslie's brand of DiChlor (which Ive added 12lbs in the last 4 days) just added more CYA.
    Yesterday's pool test from Leslie's was - FC 0, TAC 0.5, PH 7.0, TA 20, CH 180, CYA 100

    It appears that few of you experts here trust pool store testing...all the same, CYA is thru the roof. I don't have a legit test kit yet....

    My plan - to hook vacuum hose up and sweep while having filter set to waste, so I'm getting gunky water out instead of just water. I'm going to try and get 1/3 - 1/2 of the water drained, then begin to refill. Thoughts? Do's or dont's?

    Thank you in advance

    You've done some reading and sounds like you have a pretty good understanding

    If the CYA is indeed high, you do need to replace water to lower it.

    Do yourself a favor and order one of the recommended test kits. The best bang for the buck is the TF100 - see link in my sig.

    Once you get some water replaced, you should test again. If TA is really 20, you'll need to address that first. Also, pH should be in the low 7's.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Welcome!

    First, you're right, we don't trust store results, and CYA least of all. In case the message hasn't sunk in, you really need your own test kit. For super-high CYA, you might even need to do the dilution method. Don't be surprised if you end up having to do multiple partial drains.

    Second, your plan to vacuum to waste is a good one. Lose the sludge and the CYA in one go. Move the vacuum slowly. If you can see to the bottom, move the vacuum at a snail's pace and sneak up on the debris. Let the vacuum suck it in ahead of itself so you don't just stir it up and make a cloudy mess.

    This sticky thread and category.php?c=getting_started will be your guide.

    Re: Trying to clean my new green pool

    Thank you both for the reply, input and wisdom.
    BF, I'll always start my own thread, thanks.

    Ordering a test kit today, so hopefully within a week, I'll have my own results.

    I'll post again after the great H2O evacuation.

    Re: Trying to clean my new green pool

    Hi and Welcome. Keep on eye on the TA. Hopefully with a fresh water dose that number will climb... its extremely low. Edit: Not a huge concern just low TA can cause the PH to fluctuate drastically - I don't want you to be alarmed while testing or shocking to see the numbers all over the place. Once you have your own kit you'll be able to take control of your pool

    Re: Trying to clean my new green pool

    Okay, after draining between 35-50% and refilling, I'm back to within an hour of being able to continue. Should I go ahead and start the pump/filter? Should I test the water first? I just don't want to proceed and do something that will prolong this process.
    BTW, I'll have to use the pool store again as my test kit won't be here until Thursday.

    Thanks again in advance.

    Re: Trying to clean my new green pool

    Additional update - Started pump, gave the water an hour to circulate, took a sample to pool store (Leslie's) and got these readings -

    FC still 0
    PH. 7.0
    TA. 60
    CYA. 30!! Drain 1/2 the water and CYA drops 70%?? I'm guessing not...kit comes in on Wed.

    So using pool calculator, I'm adding soda wash as directed. Tomorrow ill add the directed bleach.

    See any major problems?

    Re: Trying to clean my new green pool

    I would actually only add half what is recommended in case the numbers are off or not enough time to fully circulate....You don't need to wait till tomorrow to add the recommended chlorine.

    Thanks FPM! Q. Would city water supply boost my TA from 20 to 60?

    Re: Trying to clean my new green pool

    Possibly, test the tap water and find out what the pH, TA, and CH levels are ... likely it is well above a TA of 20ppm.
