    Going with Dichlor

    Ok,
    So I am going to try dichlor/BBB method for the new Jacuzzi Spa.
    It hold 570 gallons of water. After I use enough dichlor to get my cya to 30 ish? I can go to bleach correct.

    How much dichlor should I shock with initially after start up and what FC range should I maintain?

    It has an ozonator, what effect will this have on the FC?

    Any help would be great, will take delivery tomorrow.

    Correct! That's about 4.5 oz Dichlor in 570 Gallons.

    How much dichlor should I shock with initially after start up and what FC range should I maintain?
    You can shock to 12 ppm FC. In 570 Gallons that's 1.5 oz or 3 TBS Dichlor to make it easy.

    Maintain FC around 3-6 ppm, with a min of 1 ppm

    It has an ozonator, what effect will this have on the FC?
    That will raise your Chlorine Demand (CD) to around 50% from 25%. That means your tub will drop FC in half everyday without use. However, the ozonator will help FC oxidize waste, so your CD will not raise as much when the tub is in use.

    Any help would be great, will take delivery tomorrow.
    Check out my post at the top on how to use Chlorine. You should have no problems.
