ATM Colony Saltwater 4oz – Live Nitrifying Bacteria for Reef Aquariums

ATM Colony Saltwater is a powerful biological filtration solution made with authentic, true nitrifying bacteria. Unlike common bacterial blends, Colony contains only aerobic autotrophic bacteria—the exact microorganisms responsible for ammonia and nitrite conversion in marine aquariums.

By delivering a fully pre-cultured bio-filter, ATM Colony dramatically reduces aquarium cycling time from weeks to just days. This makes it ideal for new tank setups, post-medication recovery, adding new livestock, or replacing biological media.
