Scientific Name: Dinoflagellata Pyrrophyta
Identification: A brown, green, or rust-colored gelatinous mass, filled with tiny air bubbles. It can coat any and all surfaces in a tank.
Treatment: Elevate the pH levels in the tank, reduce the nutrients available in the water, reduce the number of hours you have your tank light on each day, use extra activated carbon, and remove dinoflagellates daily through siphoning.
Prevention: A well-cycled tank with carefully maintained parameters is the best prevention.
