    How much chlorine do you put in daily?

    For non-SWG folks, how much liquid chlorine do you usually put in each day?

    I'm on week 2 of BBB, and it seems my 12k gallon pool with CYA ~ 45 needs a quart a day, maybe a little splash more. I live in sunny Houston, it's 90 degrees+ already, and my pool has no shade at all. Quart a day adds about 2-2.5 ppm, so that sounds about right?

    With a CYA of 100 I keep my FC between 10 - 12. Depending on the day between 1 and 2 quarts does the trick.

    Yes, 2 ppm, or just a little more, is very common.

    Re: How much chlorine do you put in daily?

    I'm at about 3.5 ppm per day at 35ish CYA. Still need to retest level after bumping it up. My pool had been used nearly every day by 3 to 5 kids and myself in the last 3 weeks.

    Re: How much chlorine do you put in daily?

    Congratulations!
    My pool is brand new also - first swim was May 13th!

    My CYA is about 30 ppm. I am putting in about a quart myself (11,500gal). I'm in Tucson where it has been exceptionally hot and sunny (over 105 without a cloud in the sky). When the kids are playing a lot, I will throw in 6 cups. I've been using a solar cover to raise the temperature of the pool to 88-90degF.

    Re: How much chlorine do you put in daily?

    This sounds about right, my only suggestion is that you may want to boost your CYA to 50 ppm since you are in prime sun belt part of texas and get full sunlight on your pool

    I lose about 2.5-3ppm and add 60-72 oz/day depending on sun and temp.

    Re: How much chlorine do you put in daily?

    I keep my CL around 5.5 ppm and my pool uses just over 1 ppm per day with a CYA of around +/- 40

    I put in a quart container of 8.25% bleach each morning.

    Depending on usage /rain / etc somtimes I have to add an extra half quart or so to keep the levels up.

    Re: How much chlorine do you put in daily?

    our pool was consuming 3 ppm per day at 35 ppm CYA, which was a whooping 90 oz of 8.25 % per day. I posted about increasing CYA to lower FC usage. Now at 50 ppm CYA, its consuming only 2 ppm (60 oz). Someone asked me on here when I posted, "Whats 1 ppm?"

    well, in this pool its 30 oz of bleach!

    by getting it down to 2 ppm per day, its taking 1/2 a bottle of bleach per day instead of 3/4 a bottle, which puts me at about 15 bottles per month vs 22 bottles.

    so that 1 ppm is quite a bit, actually.

    im sure on some days im still gonna spike to 3 when we are swimming a lot. But I want to keep it at about 2 ppm per day when we are not swimming or light swimming.

    Re: How much chlorine do you put in daily?

    I am in Spring, TX and my pool has no shade. I lose on a typical day 1.5. Sometimes depending on weather or swimmers 2-3. When I start losing more than 2 PPM per day that is a sign that my pH level may be high as well.

    CYA is at 50 as well.

    I typically add 24-40 ounces of 8.25% bleach.

    1.5 ppm daily. I usually only add every three days or after heavy swim load.

    Re: How much chlorine do you put in daily?

    Looks like either rain lately or extra kid usage is increasing my usage. May have to do some attempts to lower daily loss.

    i guarantee you wont regret bumping it up to 50 ppm. that will surely lower your loss to sun and the initial dose to get 'er going isnt much above what you need for 35 ppm. it cut my bleach usage by 1/3 rd.

    Re: How much chlorine do you put in daily?

    60 CYA in Phoenix, AZ; or as we prefer to call it 'The Sun's Anvil'. no shade, daytime hits 110, pool up to 90 already - 3ppm / day for me. which translates basically to a half gallon a day. since it's either a full bottle going to somewhere randomly close to half, or an open bottle going empty; measuring is not even remotely important to me. I keep a separate weekend bottle handy if I need a little boost on weekends when I do a more comprehensive set of tests.

    Re: How much chlorine do you put in daily?

    ~2 ppm per day, give or take with CYA at 40.

    Works out to about 2 121 oz jugs of 8.25% every three days. Sometimes it's 3 jugs every 4 days depending on how often the dog goes for a swim

    Re: How much chlorine do you put in daily?

    About the same for me. CYA around 50. 2+ppm per day. One jug of 8.25 raises my ppm by 3. So I add a jug for two days then skip a day unless testing reveals it needs it more frequently.
