Thread: When do YOU shock?

    When do YOU shock?

    I'm just curious and would like a range of opinions as to when you typically shock? Do you always shock after a heavy swim load or decent storm? Or do you rarely shock and just monitor your daily FC loss, and if it stays consistent you don't worry about it. Just curious?

    Thanks,
    Alan

    Re: When do YOU shock?

    personally i haven't shocked in 2 years. my understanding of the bbb method, is you
    never need to shock unless you get algae or are having over night fc loss.

    Re: When do YOU shock?

    Here's a quote from Pool School:
    Shocking the pool will eliminate algae, combined chlorine (CC), and any other organic contamination. If you have algae, or the CC level is above 0.5, or the free chlorine (FC) level is zero, you should shock the pool. Many people also like to shock the pool when the FC level falls significantly, as it often does after a major storm or large swim party. This is done even if FC doesn't get all the way to zero, just to be sure everything is all right. If you are maintaining proper FC levels there is no need to shock weekly, or on any other regular schedule.

    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.

    Re: When do YOU shock?

    on another note, i noticed when i went to the pool store the other day, i know many
    don't believe in the pool stores, but i live in a small town and the owners of the only
    pool store here have been at it for many years. i usually deal with the owner and he
    knows what i am doing as far as the bbb method and agrees. the truth is i can buy
    liquid chlorine and baking soda from them cheaper even than wal mart. so to the point,
    when they get summer help to do their water testing i have noticed that no matter
    what the results are, the first question they ask is when did you last shock?
    the last sample i took in tested perfect (her words), and yet she asked when did you last shock?
    when i said 2 years, she had no clue what to say as the owner and i just laughed.

    Since we all know that shocking is a process and not a one time addition of product (called shock), I wouldn't consider a preemptive, one-time, purposeful rise of FC after a pool party to be "shocking". Just sayin'

    Re: When do YOU shock?

    If I find algae in the pool I will shock. But if FC has been a bit low due to lack of attention, or a big rain, or weird stuff in the pool (vultures then weird bits of tissue in the water.... eww) then I will just run the FC up a bit higher than normal and let it come back into range.

    Then if FC usage is high after that, I'd either shock or take a look at the boulders around the pool and in the waterfall since they can start to get algae above the water line. A light spray of 50% bleach and some casual scrubbing will get things back to normal, though the rocks are so rough that killing all the green on then is impossible.

    Re: When do YOU shock?

    Pretty much as stated above - if I have a serious issue, such as when I put my new liner in this spring and had to fill instead of just topping off as usual. We have well water. Otherwise, something serious has to happen before it is necessary - just regular maintenence and testing keep it pretty well evenly normal

    I haven't yet. Only been here since October. I did raise FC up a bit before we went on a trip, but it wasn't shock level.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
