I was just wondering if anyone had a rule for the amount chlorine to add when getting out of the hot tub. I.E. two people in for one hour add X ounces of chlorine. I ask because last week we had 4 people in for about 2 hours, I added 2 ounces when we got out. Checked it the next morning and it was 0. Seamed like it used a ton of chlorine over the next few days. Just wondering if there is some sort of chart to follow to counter act this. Thanks in advance

Use this How do I use Chlorine in my Spa (or pool)?
quoted in there is this "the rule of thumb is, you'll use approximately 7 ppm FC per person per hour in a 350 gal tub "
so if you had 4 people in there for 2 hours than you need about 56ppm to counteract that.

Thank you dunginhawk for the reply. Man that’s a lot of chlorine when I’m accustomed to using 1 to 2 ounces at a time
I seriously doubt it would require that much. Id start with half of that and see what it looks like in an hour.

My tub uses a min of 1/2 oz. of 10% Cl per day with no use. When used I add 1oz per person per hour. So 2 people I add 2.5 oz.
See JasonLion's and Chem Geek's answer here Chlorine consumption per bather
From the thread:
According to my pool math calculations, this is also 3 fl oz of 10% bleach, or 2.5 oz of 12% chlorine.
So the rule of thumb for me is 5 fl oz of 6% bleach per person-hour. This seems to be pretty accurate in my tub.

My wife and I shower before getting in and then use it for about 40 minutes. When we get out I add 3 oz and it is usually right where I want it the next night when we go to use it.
I usually dont have to add any chlorine at all with my SWG at 2800ppm salinity. It can handle my 30-45 minutes per night all by itself.. Once i throw the wife and kids in there then I need to start suplementing, about 4 oz (6% bleach) after each family soak
