Pawfly Internal Aquarium Filter 160 GPH – Quiet Submersible Bio Sponge for 30-60 Gallon Tanks

All-in-one filtration for 30 to 60 gallon tanks

The Pawfly internal aquarium filter combines mechanical and biological filtration through a fine sponge. This design traps debris and wastes while protecting smaller inhabitants like shrimp and fry, contributing to clearer water and a healthier-looking aquarium. The result is a visible improvement in water clarity and overall tank vitality without stressing delicate creatures.

Why this filter stands out

• Fine sponge filtration provides both mechanical and biological cleansing, helping keep the water pristine.
• Protected intake minimizes the risk of shrimp or fry being drawn into the filter.
• Compact footprint fits in tight spaces while delivering dependable performance.

Flow, outlets, and customization

The unit features a 160 GPH water pump and two outlet options: a drenching pipe and a spraying pipe. A simple knob lets you dial in the flow to suit your tank, balancing circulation with surface movement for a healthy environment.

• Two outlet styles give you flexible placement and water distribution.
• Adjustable flow lets you tailor filtration to your tank setup and inhabitants.
• 8 W power provides steady operation without heavy energy use.

Aquatic oxygenation and bubbles

Comes with clear airline tubing for easy air entry, producing numerous bubbles that help with gas exchange. The additional bubbles can contribute to brighter water and livelier activity, especially during feeding and daily routines.

Size, care, and suitability

This filter is designed for tanks in the 30 to 60 gallon range. Its dimensions are compact: about 1.65 inches wide and 6.8 inches tall, with 8 W of power. For maintenance, detach the pump from the filter, remove the impeller cover, and rinse the sponge using only aquarium water about every two weeks. The bottom panel opens to access the sponge for quick cleaning.

Real-world use cases

Ideal for community setups with ornamental fish, shrimp, or fry where gentle filtration is preferred. The combination of clear water, ongoing circulation, and added oxygen can support active feeding routines and steady tank health, while remaining unobtrusive in quiet living spaces.
