Cascade Powerhead Driven Sponge Filter by Penn Plax
Sponge filtration for small aquariums: The Powered Aquarium Nano Sponge Filter is designed for fry, shrimp, and small fish. It features two ribbed sponges that effectively trap floating debris and impurities without creating strong suction that could harm smaller or weaker fish and shrimp.
Integrated power supply: This sponge filter comes with its own power supply, eliminating the need for an additional air pump. This simplifies setup and ensures efficient filtration in your aquarium.
Beneficial bacterial colonization: The two sponges provide ample surface area for the colonization of anaerobic bacteria, helping to establish a well-balanced biological filter.

Great for my shrimp tank. The filter works quietly and doesn’t stir up the water too much. My shrimp are active and healthy since I added it. The sponges stay clean and the flow is gentle.

Easy to set up and runs smoothly without needing extra parts. Works well for my small community tank with neon tetras and baby guppies. Sponges need occasional cleaning but are effective.

Perfect for a nano tank. No strong suction, so my tiny shrimp aren’t stressed. The built-in power is convenient and the filter maintains good water clarity.
