Welcome to our forum.
The method I have used and recommended for twenty years is to simply add a small amount after each use. If you go a week without using the spa, shock it at the end of the week.If you have ozone and use N2, you can keep the chlorine down to 1PPM and things should be rosy. That could be a teaspoon after each use. I don't know the exact amount you would have to add, but here is how to find out:Bring the chlorine level up to 2 PPM if you have ozone, 3 - 5 if you do not. Use the spa. Add two tablespoons of dichlor. Test the following evening to see if you have the above readings.If too high, cut back. If too low, increase.?Repeat. 8-)
Chas, I've never heard this method described before. Do you mean add two teaspoons of dichlor? I usually shock with two tablespoons of dichlor.
I think these suggestions may help me as well. Good post. I was wondering if after use, when you add the 1-2tsp of dichlor, if you keep the tub running or not.
