Evolution Aqua Pure Aquarium Bomb

PURE Aquarium Bomb is 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 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.
