4 lbs of ascorbic acid should work.
Ascorbic acid doesn't always do well with copper. So, it might not work and it might even create more stains.
You're at risk for an algae outbreak due to the low fc. So, you want to complete the process as soon as possible or begin to use some chlorine or poly 60 algaecide.
If you get algae, it's going to be difficult to treat without causing copper stains.
Poly 60 should be available locally. Just look for the ingredients listed.
Sequestrant should be available locally. Don't get edta based sequestrant.
Take a picture of the cartridge before you clean it so we can see what it looks like. The colors can help identify the metals in the water. Turquoise is copper, brown is iron, silver is black or grey.
Be careful about raising the pH. What are all of the chemistry readings?
