Cyanobacteria are microscopic organisms that convert organic substances such as excess food, coral decomposition, or fish death. They grow quickly and endanger the corals in the aquarium. They are constantly present in the aquarium and can never be completely eliminated, but they can be significantly reduced.

DOSAGE: With the provided syringe, apply 1 ml of Haquoss H19 liquid to each cyanobacteria colony (each ml treats 5-6 square centimeters of surface).
