dinos are dinoflaggelates. Brown snotty stringy algae-like, sometimes bubbly. A diatom bloom is the brown "dusting" many people get when they start the tank. Both blooms are usually pretty temporary, and very common on newly established tanks. They usually just go away shortly as the tank starts to mature.
i have a lot of algae on the front of my glass that i cant get off with a magnet cleaner. i have to use an algae scrapper to get it off. does anyone know what kind of algae this is? its hard brown dots all over my front and sides of tank.
