Re: Ascorbic acid, chlorine and TA (long)
I can answer the chlorine question - chlorine is used up getting rid of the ascorbic acid. When I was first using the ascorbic acid I asked a guy from the chemistry strore what would happen if I still have chlorine in the pool and add the ascorbic acid - he said nothing - it would just waste some of the ascobic acid, because the chlorine will eat it up, that is why you should have your chlorine at 0 to start. I never had the alkalinity rise when I was doing the stain treatment - The ph goes way down, and is hard to raise after the treatment. I don't know what would have raised the alkalinity, what is your ph? Did you add any baking soda to raise your ph? I am not at all a chemist, but to lower your alkalinity your want to gas off the carbonates. The only thing I can think of is if you added baking soda to raise your ph, you would have also raised your alkalinity - you can use borax to raise the ph, it won't raise your alkalinity.
