I think another classic mix up with chemi clean and chemi pure is taking place here. This bush has been run around so many times that I am getting dizzy (ier). I wish they would change the name of one of them.
I think I have this right - chemi clean is for treating your tank for cyno algea and then the whole water change regime come into play.
Chemi pure is sort of like a super carbon that stays in your filter or passively in the sump to help maintain water quality.
In a nut shell anyway - as long as I don't have the names backassward.
