    Frequency of adding Bleach and shocking

    Question, with BBB, is adding bleach a daily ritual? I am trying to understand how much I would need if I were in a maintain mode of say 4.0 with a 40 cya on a 10K gallon pool? My concern is my work schedule where I may miss 1 possibly 2 days of adding. Also when adding can folks swim. Got kids that like to swim at night. Lastly can non chlorine shock be used or is that taboo. Chlorinator has me spoiled but now I am convinced my 3 algae fights last season were due to chlorine around 3 and CYA around 100 where pucks and acid took me to.
    Also when shocking to shock level how long does it take to dissipate, right now the dichlor is out in about a day, but will bleach go if CYA is lower? I think yes, but not sure

    effect on pool equipment.

    Re: Frequency of adding Bleach and shocking

    Adding bleach will PROBABLY be a daily ritual. There are ways around it, the Liquidator, salt water pool, or chlorine injection systems.

    I would not recommend a non-chlorine shock.

    You still keep CYA around 40 with bleach, so no change there. Bleach won't add more CYA like the dichlor will.

    Re: Frequency of adding Bleach and shocking

    Yes bleach is a daily ritual. If u use a solar cover you can dose a little higher and cover and it should be ok when u r gone. Add the bleach after evryone is done swimming. Leave the pump running for at least an hour.
    Thereis no effect on pool equipment. Once in your water, all forms of chlorine do the same thing. I highly doubt that level had anything to do with highlights or spray tan unless they were done that day.
    Non chlorine shock is an expensive and unneccessary product.

    Re: Frequency of adding Bleach and shocking

    I am not sure if this will help you with your pool, but for my pool with a Cya of 50, I add almost a 184 oz jug every 2 days. My fc goes up to 8ppm and is usually at 4ppm when I add bleach again. Pool is in full sun, very light bather load....As far as shocking, with a high quality test kit, you are able to know what's going on with your water at any time and in combination with the pool calculator. You can make any necessary adjustments to avoid having to routinely shock your pool!

    Daily or every other day to add bleach.

    If you keep the FC level up, you may never need to shock.

    Dichlor is good to have around if you need to replenish CYA due to splashout. I wouldn't use it as my normal source of chlorine. You've seen what high CYA can do, so no need for me to go into gory detail.

    Rob N, does the 8 ppm bother swimmers? How high can you go before it is dangerous or takes on whitening characteristics on suits and such?

    Is there no one else at your house that can add bleach, it is not exactly rocket science. After a bit of time you can estimate your seasonal daily rate and only test a couple of times per week.

    Re: Frequency of adding Bleach and shocking

    I add bleach twice a week...CYA is 60, I bring the level up to 10-12ppm, and it drops to 5/6ppm by the next "pool cleaning day" (add bleach, run pool cleaner, hose off cartridge filter, add water) It's been working for a few months now, and my 5 kids swim at LEAST once a day. I check after a hard rain too though so sometimes I add a little extra in between pool days.

    Re: Frequency of adding Bleach and shocking

    I've not had problems with suits getting wrecked any faster than normal.....my kids don't rinse them either. Each kid goes thru 2-3 suits a season (March-Nov here in FL.) I don't think that is too bad for as much as they swim (and wrestle in the pool and yank on each others suits, LOL)

    No problems whatsoever, no chlorine smell, no eye burning and no bleached out swim suits. The water feels great and looks crystal clear and sparkly!!!!

    Good advice above from some people that have a very good grasp of what BBB is all about. I chlorinate every 2 days by adding about 4-5ppm to my pool.....keeps it in a 4-8 range with a CYA of 50ppm

    Re: Frequency of adding Bleach and shocking

    Thanks, much more comfortable. Only issue is local walmart is clean out of bleach and borax, hmm wonder why, they were even out of the 12 lb bags of baking soda. My TF100 will be in tomorrow, thanks again. I have been doing massive amounts of reading on this site and got a lot of insight from a good community.

    My Wal-mart has been out-of-stock on the large GV bleach my last two visits. Fortunately, the FLPS across the street has 12% LC @ $9/2.5gal carboy. $4 deposit on the carboy is refundable. Cost is almost identical and less lugging, no bottles.

    That depends on the CYA level of your water.

    Once you get the relationship, you can set a target and let pool calculator crunch the numbers.
