When I first started getting my water tested at the shop I was told to add a Non Chlorine Oxidiser (Bioguard Oxysheen) whenever I had CC's.
At what level of CC is it necessary to use an additional chemical as opposed to letting the FC do its work?
Today ( it's winter here ) I noticed a small amount of CC while doing my test so I added some of this expensive chemical.
If I keep an adequate level of FC is it even ever needed to add anything else to deal with the CC?
