OK.. Just finished the Ascorbic treatment... Worked as planned.... I have well water and for the past 5-6 years have had issues with metal stains (which I will have to live with)..

IF I Keep my CL levels in their correct (CYA) range(s) and keep the PH in the 7.2-7.4 range, ( I rarely need to shock throughout the year once things are in control) Do i need to be adding the sequestrant and utilizing the CuLator packet ?

I can deal with JUST keeping the metals in the water
