Automatic Chlorinator - Recommendations, please

June 7th, 2007 · 3 Comments

Greetings,
I’m nearing the bottom of 18kg (40lbs) tub of granulated chlorine, and
before I buy another I’m wondering about adding an automatic
chlorinator.
I plan to continue with chlorine for sanitation, and I’m looking for
advice on selecting and using a feeder for 75mm (3inch) tablets.
Any gotchas?
Thanks In Advance!
Peter

    Have you considered converting to a salt water pool? And eliminating
    the need for chlorine? Once converted, other than an occasional shock
    treatment, you don’t need any chlorine. I have an above ground
    16×32. I had to add about 300 pounds of water softener salt (Cost
    about $30.00) and purchased a chlorine generator from Cabella’s
    (www.cabelas.com, then search for ‘chlorine’) for about $150 and
    eliminated my need to purchase chlorine products, other than a
    weekly ‘maintenance’ dose of shock. The chlorine generator converts
    the salt to chlorine and when it is used up it reverts back to salt
    and can then again be converted. Kind of an endless system. Most
    chlorine generators will run close to $600, making this a high priced
    venture, but having found an affordable one from Cabella’s makes it
    worth it. Cabelas offers the Intex Chlorine Generator for $144.99.
    You can also fine them on E-bay for a slightly higher price. BTW, the
    recommended salt content is about one-tenth the strength of the salt

    water in the ocean. Just be careful if you also have metal parts in
    your filtering and heating system as corrosion can become a problem.
    There is also quite a bit of info available on the internet. I’m two
    months into mine and so far, so good. No chlorine purchases for me.

    I recommend a rainbow 3 inch tablet auto feeder. rainbow is owned by
    pentair pool products. it comes in an offline and online version and
    both are pretty easy to install. if you have a heater, you must install
    a check valve to prevent backflow into the exchanger. it will explain
    this in the installation instructions. These are great devices, the
    only problem i see with them, is people tend to only use the tablets,
    and this can cause a rapid increase in the cya levels of the pool.
    i’ve seen them as high as 300 ppm.

    Hi Peter,
    I had never heard not wise to put tabs in the skimmer basket - why
    would this be???
    We have an automatic feeder - I fill it once a week or every other week
    depending on our weather - and I set it, and it runs. I didn’t use it
    last year - had constant problems but this year after the new
    filter/sand we seem to have a nice clear pool with minimal maintenance.
    I was constantly told to shock last year (our first year) - oh and we
    had phosphates, so that was a good suggestion to have that tested!
    Sincerely,
    Pam
