Marie, I have never seen anything to the contrary about using stain removers with SWGs. If anything the low pH might help in removing some scale from the cell (not really sure but it seems like it should since calcium is a metal). I would think that the SWG should be turned off until the process is done beause chlorine will depleate the ascorbic acid. Probably best to use bleach to bring the chlorine levels back up and then turn the SWG back on. Poolsean would be the one to ask about this.

Ascorbic acid is ascorbic acid! Here is the web site that sells 5 lbs for $45. You can use thier stain remover, but you are paying more for the convenience. I'm not sure of the shipping cost.

Is the Ascorbic Acid approach ok to use with cartridge filters? If not, then what?

It is fine to use with ANY kind of filter. I have a cartridge filter and have used it.
