I have a question though,do you know if chlorine will kill a pythium infection? What about fungus gnat larvae infestation of roots? My feeling is at high enough concentrations it will, but is 2ppm high enough for that? And 1gram/100gallons is 2ppm total chlorine, not free chlorine, the free chlorine might have to be higher to kill them?
