Instant Ocean BIO-Spira

Instant Ocean BIO-Spira (with patented nitrifying bacteria) accelerates the establishment of the bio-filter in newly set-up saltwater aquariums. The live bacteria start working immediately to provide a safe and healthy environment for your fish without the long wait. BIO-Spira can also be used after water changes, when adding new fish, or after medicating. Effectively reduces dangerous ammonia and nitrate, and prevents "new tank syndrome". Patented mix of Nitrococcus, Nitrosomonas, Nitrosospira, and Nitrospira is proven to work. 100ml treats up to 30 gallons.
