CPR Aquatic's Nano and Mini Tumblers provide an ideal solution to active filtration in an aquarium. Utilizing an efficient upward flow design for thorough and gentle fluidization, these reactors can be used even in restricted spaces, consuming 3-4 watts of power. The simple lid assembly makes media exchange and maintenance a breeze. Their small size and adjustable fluidization help optimize the use of filtration media, increasing the tank's cleanliness with less media usage over time. Compatible with a variety of media, such as bio-pellets, and ion-based resins, the Tumblers are an easy-to-install powerhouse addition for any system - for fine media, such as Chemipure or Phosban, an additional filter pad is required.
