So I did an Ascorbic treatment last week to remove some metal stains. The treatment worked well and I used 2lbs of AA and 2 quarts of the pink stuff.
After rebalancing my water I can't keep any FC. Last night I had an FC of 0 so I added 2 jugs of liquid chlorine (bleach) and this afternoon I had FC of 0!!!
Any idea of why?? Do I need to shock?
