Tetra Safe Start Plus creates a biologically active environment to allow fast introduction of fish into newly set-up fish aquariums. Tetra Safe Start Plus reduces dangerous ammonia and nitrite and prevents new tank syndrome for a healthy start for fish in all freshwater aquariums. Contains live bacteria that start working immediately to provide a safe environment for new fish. Tetra Safe Start Plus can also be used after a water change, when adding fish or after medicating. "Cycling" your tank means growing the correct, healthy bacteria on a new filtration system to remove dangerous toxins. New filters are sterile and take 30 to 40 days for bacteria to naturally form. This concentrated formula speeds up the cycling process by accelerating the establishment of beneficial bacteria from the start for instant, safe results. Size: 0.26 lb
