Replacement Cartridge for Penguin Mini & 100B - 6 pk.

3 Reviews


Each preassembled Penguin Filter Cartridge filters aquarium water through a double thick polyfiber pad which traps more dirt and debris, faster. The filter cartridge is packed with super-efficient pure Magnum Activated Carbon, it keeps working long after most carbons stop. It's better than a bag: just shake and rinse. The patented ribbed backing evenly distributes carbon for maximum water to carbon contact. No bypass, no tea bag effect, just crystal clear, crystal clean aquarium water. Each Penguin Filter replacement cartridge includes a foam pad and carbon for superior mechanical and chemical filtration. The easiest way to superior aquarium filtration.

MiniTank MarineLand filters


I was unsure of what I would think of this little 4 gal. tank... after setting it up and adding my Betta and my Mystery Snail - it's great! Naturally the Penguin Power Filters work perfect! I also have a marineland 10 gal. tank for over 5 years now... wouldn't have any others!



A little better and more durable than the larger sizes but still cheap and falls apart fast!

Excellent item for a great price!


Our local Petco has these filters priced at $12.99 for a 3 pack! I bought these for $7.49 for a 6 pack! Twice as many for about half as much.... I'll never shop anywhere else for pet supplies! Thanks!!!
