Fast acting live filter bacteria. Ideal for new aquariums. Joining the award winning PURE Aquarium range is PURE Aquarium Bomb, unique, clear, live bacteria gel ball for use in aquariums. A much larger single treatment dose of live nitrifying bacteria designed specifically at cycling new aquariums and making them ready for fish. It also rapidly combats water quality emergencies in new and established freshwater aquariums, when life threatening levels of ammonia and nitrite are detected. Beneficial bacteria inside the filter can also be lost through cleaning media under the tap, replacing mature media with new, or the use of medications. Increased fish numbers, uneaten food and dead, decaying fish can also lead to levels of ammonia and nitrite. Key Benefits: Matures new filters rapidly. Cycles new aquariums. Repairs bacteria colonies. Provides rapid nitrification. Eliminates New Tank Syndrome. Simply add to your filter. Please note: Not intended to clear green water. Simply place PURE Aquarium Bomb directly into the main aquarium or better still into a space within a biological filter. You should then use one bomb per 200 litre aquarium, and will even work with a full stocking of fish. Add one Pure Aquarium Bomb into the water or filter. Ideal for aquariums up to 200 litres volume with a full stocking of fish.
