At Marineland, innovation powers everything we do. From industry firsts to industry standards, Marineland products are designed with both performance and style in mind. We push precision and power beyond the expected and listen to our loyal customers to make our products even better. We do this because at the heart of our innovative spirit is a desire to help hobbyists everywhere do more, create more and, most of all, enjoy more. Make it Marineland. As it rotates, the BIO-Wheel filter exposes beneficial bacteria to the air which has more than 30,000 times more oxygen than the oxygen already dissolved in the water. More oxygen means more bacteria working harder and faster to keep your tank ammonia-free. The BIO-Wheel filter never clogs or needs to be replaced. The Bio-Wheel Penguin Refillable Media Cartridge is better than media bags. The patented ribbed design keeps the media of choice evenly distributed for maximum water-to-media contact, and the snap open and lock tight design ensure no media spillage. Refill your Bio-Wheel Penguin Refillable Media Cartridge monthly for best results.
