    New pool owner... lets get it started owwww! :)


    What's up guys and gals, I'm starting my first "SLAM and maintain" to make my pool clear again. I've had the dilemma of my local Leslie's pool store racking up a bill after giving them multiple attempts to clear my pool... Time to take matters in my own hands.

    I've ordered my TF-100 test kit and should be here Thursday this week, also bought 25 gallons of 8.25% bleach (Wal-Mart brand), and some muriatic acid from HD.

    - First question, when do you take readings to get your "shock level" reading vs. "FC" reading?



    Readings (have a Leslie's /Taylor test kit)
    FC: 0
    CC: 0
    PH: 7.8
    TA: 90~100
    CH: should I be concerned with this yet?

    Maybe I will be the only one, but I don't understand what your asking exactly. Shock level reading vs FC reading? Shock level is just a term for raising your FC to a higher point to destroy organics, but your still testing your FC.

    Re: New pool owner... lets get it started owwww! :)

    What is the current condition of your pool water?

    In your first post I see you don't have a CYA reading, so that will be something to definitely do, then you should just go ahead and use your new tf-100 and run all the tests.. (can skip the fas-dpd chlorine test if your not adding any chlorine you know it will be zero, and you can confirm that with your OTO (yellow color matching test)

    So to start your slam, you will need to get your CYA reading and use the CYA/chlorine chart to figure out your SLAM level. Use pool math, calculate how much chlorine to add to raise your FC to your newly found SLAM level. The standard beginning time between tests is 1 hour. When you retest your FC after that first hour...use your test results to raise your FC back to SLAM level.

    After a couple of hours, and a couple of tests, you will get an idea of how fast your chlorine is being consumed and can adjust time in between tests accordingly. Some pools will consume 7 ppm in just an hour, while others will only consume 2. Just test often enough (as possible) to keep FC levels at or above your slam target for as much time as possible. You will also consume more chlorine during the day from sunlight than you would during night when the sun's down so your time will vary based on that too.

    The SLAM line is listing his target FC for the slam process, as determined by his CYA level. So that line isn't a reading, it is just a target. He is listing it each time so that people reading the thread don't have to continually go back and reread previous posts to find out what the target is.

    Only if it is too high.

    With 70 CYA, FC level for the SLAM is 28.

    Congratulations on ordering the TF100 You are already way ahead of the game!

    Be aware, the Pool store is rarely correct on the CYA test. Please post a CYA test from the TF-100 once you get it and we can help you from there.
    If it is high, you will likely have to drain some water. 70 is too high IMO already and I would drain ~40%. I wouldn't do anything until you test for CYA yourself.

    This is my own CYA test result, not the pool store. The kit I currently has the ability to test CYA, (7ml pool water then add reagent R-0013 to increase level to 14ml, wait til black dot slighly disappears)

    If I do lower and refill, what CYA level should I shoot for?

    Are you sure about the slightly disappears part? I have never heard of any kit testing CYA that way...it's always been when it just completely disappears. If it's slightly disappears at 70, you would be less then 70 if you kept filling until it completely disappears.

    Your target CYA will depend on your pools condition...green swamp or blue and cloudy, as well as water cost and if you want a lower slam target(less bleach) or if your okay with higher slam target (more bleach).

    Check into your CYA testing instructions and also I haven't seen you say what condition your water is yet.

    From the online instructions of a Taylor K-2006 test kit. "Just disappears = fill until it starts disappearing then little by little until it's gone.
    Cyanuric Acid Test

    1. Rinse and fill CYA dispensing bottle (#9191) to 7 mL mark with
    water to be tested.

    2. Add R-0013 to 14 mL mark. Cap and mix for 30 seconds.

    3. Slowly transfer cloudy solution to small comparator tube until
    black dot on bottom just disappears when viewed from top.

    4. Read tube at liquid level on back of comparator block. Record
    reading as parts per million (ppm) cyanuric acid.

    Yes this is what im doing.. I was able to get home earlier today and found that my test came in, CYA adjusted by 10ppm (is this common?), pool is cloudy green/bluish color.

    FC= .5
    PH= 8.0
    CC= 1
    TA= 95 ~ 100
    CYA = 80

    I would like to get my CYA to 55, so im going to remove/refill tonight.

    Ok current today, out sick from work. Drained water and refilled do adjust CYA levels down, and current levels are as below

    FC= 0
    TA=95 ~ 100
    PH= 8
    CYA= 60
    @2100 added 21 Oz of Muriatic Acid (31.35%) to lower PH levels down to 7.2ppm

    So are you sticking with your cya at 60 for the SLAM process? Not sure if your last post was just an update post or if you were looking for guidance.

    Retest PH after 30 min and if it's down to 7.2-7.5, begin the SLAM. If sticking at 60 CYA you can start tonight with 24 as your slam target.

    Start your SLAM tonight. You will get the added benefit of working under the cover of darkness.

    waited an hour to verify my PH, as below..

    FC= 0
    CC=0
    CYA= 60
    PH= 7.2

    I figured i shoot high for mustard algae at SLAM level of 34, poured in 387oz of 8.25% bleach. Check FC in an hour and update you guys again , then off to bed

    An hour was plenty of time to circulate for your pool, that's not the problem.

    The math was right for the 387 ounces. That means you either got some REALLY REALLY fresh and over strength bleach, gallons are wrong for your pool, or testing error. If you added 387 ounces and got up to 50ppm and your gallons are accurate....it would have been more like 12.5% strength in those bottles.
