Keep your Marineland Penguin filter running smoothly with these replacement bio-wheels! This 2-pack is made to fit Penguin 200, 200B, 350, and 350B models – replacing part number PRBW2350B. The wheels have a reinforced PP frame that’s more durable and less likely to warp than some standard versions, which helps maintain steady rotation for effective biological filtration. They’re easy to install – just pop out the old wheel and clip the new one onto the axle. No tools needed. Having two means you can swap them during maintenance or keep a spare on hand. Perfect for aquarists who want reliable filtration without buying a whole new filter. Just make sure your filter model matches before ordering. Your fish will thank you for the clean, healthy water!
