xEffortless, ready-to-use filtration for your Marineland Penguin filter
Marineland Rite-Size Penguin Power Filter Cartridges Size C are designed to keep mid-sized aquariums clean with minimal effort. These ready-to-use cartridges arrive pre-assembled for quick, clean replacements and feature color-coded Rite-Size packaging to help you select the right cartridge for your Penguin Bio-Wheel filter. If you own Penguin 170, 200, 330, or 350 power filters, Size C offers a convenient fit that supports ongoing tank maintenance without guesswork. In real-world use, many keepers notice tank edges that look crisper and water that feels clearer after a routine cartridge swap.
The cartridge is built around a robust three-stage filtration system that combines mechanical, chemical, and biological filtration in one unit. A ribbed backing ensures even distribution of the media for maximum water-to-carbon contact, helping to optimize flow and filtration efficiency. Inside, Black Diamond Premium Activated Carbon targets impurities and odors, contributing to a more visually appealing, clean-looking aquarium water. The BIO-Wheel in the cartridge adds a biological filtration component, promoting beneficial bacteria growth that helps manage ammonia and nitrite concentrations as part of the filter’s ecosystem. The BIO-Wheel has 50% more surface area than earlier designs, which may enhance overall filtration performance over time.
