How long do i wait to put the Carbon back in, I usuaully move all fish to a sick tank, but i got fin rot on one of the Oscars, so i decided to just treat the whole tank, with Fungus Clear from Jungle, is that a good treatment to begin with, It was all Petsmart had at the time, and didnt want my fin rot to get serious. The carbon has been about for about a day, when should i put it back in?
