Pour the water conditioner into the water and 15 minutes later add the bacteria activator, then add the fish.

The water conditioner removes harmful substances from tap water and the bacteria activator provides beneficial bacteria that will break down pollutants.

Without the bacteria activator, the water becomes enriched with toxic ammonia and nitrites.
Ideal for freshwater aquariums populated with fish, shrimp, and water turtles.

Contents: JBL Biotopol water conditioner (15 ml) and JBL Denitrol activator (15 ml) for 10 to 60 liters of aquarium water.
