API Quick Start, 4 OZ

API® QUICK START bacteria enriched with nitrogen allow for the immediate addition of fish, as they instantly start the aquarium's natural cycle with beneficial bacteria, which convert toxic ammonia into nitrite, and then into harmless nitrate to help prevent fish loss in your tank.

Best used when starting a new aquarium, after water changes and filter changes, and when adding new fish to an existing tank.

API QUICK START bacteria can be used in both freshwater and saltwater tanks.

Add 10 ml for every 10 gallons of aquarium water.
