Nyos Bacto+ is an all-in-one bacterial preparation with a broad range of applications. It reduces nutrients (nitrate, nitrite, ammonium, ammonia) and eliminates sludge, detritus, and organic contaminants. The result is crystal-clear, clean aquarium water. When restarting, Nyos Bacto+ shortens the running-in phase.
