Ascorbic acid, chlorine and TA (long)

[EricF]

Thanks for the reply.

No bicarbonate...my alkalinity is naturally high and that is one additive I don't even have around.

No matter the cause, it looks like I am doing the "Lower the Alkalinity Dance" once again. Good thing I have a lot of muriatic acid. My fill water in eastern NC has an alkalinity of about 210.

Hopefully the stains won't come back!

Oh, and my chlorine was 0 to start. I just was not expecting the chlorine demand after treatment, or the increase in alkalinity.

Thanks,

You can see the best way to lower your alkalinity in this thread:

You will start to hold chlorine when all the ascorbic acid is out of the water, it is always good to put in maintanence doses of metal free each month too.
