Bio-Fil 2™ Wet/Dry Filters include Bio-Pin Balls® and provide the most effective method of aquarium biological filtration available. Excellent choice for fresh or saltwater fish tanks. Bio-media helps increase oxygen content of the water.
This design incorporates an efficient drip plate for full distribution of water over the bio-media, an overflow passage, and a larger biological chamber than other brands. A removable post filter sponge allows for an expandable sump to accommodate protein skimmers or other filtration accessories. The rugged 1/4" acrylic construction is durable, easy to install, fits most pre-filter drain lines and is designed for fish tanks up to 240 gallons.
