Ziss Bubble Bio Moving Bed Filter

Creates a Strong Colony of Beneficial Bacteria Tough and Durable Construction Great Filter for Turtle Tanks The Ziss Bubble Bio Moving Bed Filter is the first of its kind that runs off of an air supply and fits inside the aquarium. These units are great because they come with an easy to remove intake sponge and the media starts moving from day one. While this filter runs, the media inside is constantly rubbing against itself which keeps the media clean and allows the strongest bacteria to thrive. With oxygen traveling through the air intake combined with strong bacteria - these filters can handle large amounts of ammonia in comparison to other types of filters. 2.95 inches x 9.8 inches Filter Volume : 600ml We feel this filter is best suited for 20 gallon tall and larger aquariums. One Ziss Bubble Bio can handle up to 40 gallons by itself. Best combined with a sponge filter or hang on back as this will handle your biological load in the aquarium and some mechanical, but if you want crystal clear water you'll want to add a mechanical filter like a sponge filter or hang on back to the mix.
