Which Penguin filters fit Rite Size C cartridges?

MarineLand Rite Size C cartridges fit Penguin PRO Power Filters 275 and 375, as well as original Penguin Power Filters 200 and 350. Compare your filter’s model number with these four models to choose a compatible replacement.

How do these cartridges filter aquarium water?

Each cartridge combines mechanical filtration with chemical filtration using a double-thick poly-fiber pad and activated carbon. The pad catches debris and waste particles, while Black Diamond Premium Activated Carbon filters water chemically. MarineLand identifies the cartridge system as three-stage filtration.

• The ribbed backing is patented and helps spread the activated carbon evenly within the cartridge.
• The filtration materials are built into the cartridge for replacement as one pre-assembled unit.

What comes in the Rite Size C bundle, and how does it install?

The bundle contains 18 pre-assembled cartridges that slide into place in a compatible filter. Their ready-to-install design avoids assembling the cartridge during a replacement and is intended to make the change fast and dry.

• Quantity: 18 Rite Size C replacement cartridges.
• Installation format: pre-assembled cartridges that slide into the filter.

This bundle suits aquarium owners using a compatible Penguin PRO 275 or 375, or an original Penguin Power Filter 200 or 350, who want replacement cartridges with both mechanical and chemical filtration. Its model-specific fit and pre-assembled design make it a practical choice for routine cartridge changes on those filters.
