Internal Hanging Nano Protein Skimmer

Maintain a pristine marine environment with this expertly designed internal protein skimmer, a professional-grade solution specifically for exquisite small marine fish tanks. This internal built-in hanging cylinder type skimmer utilizes advanced DC needle brush pump technology to deliver sensitive and efficient sewage discharge in a compact form. Measuring only 82mm by 53mm, its slim profile is perfectly suited for placement in back filter grids, ensuring high-performance filtration without occupying valuable space in your display.

Key Features

• Efficient DC Needle Brush Pump – Cleverly combines the motor with the barrel body and a titanium alloy shaft to create fine bubbles for high-efficiency waste removal.

• Ultra-Compact Design – With a footprint of only 82 x 53mm, it is ideal for nano aquariums where space is at a premium.

• Versatile USB Power – Operates on a safe 5V 1A low-voltage DC supply via a universal USB interface, allowing for operation via standard chargers or even power banks during outages.

• Silent Operation – Includes a built-in newly designed silicone muffler to ensure stable and quiet performance.

• Precise Water Level Control – Features a knob-type water level regulating valve and a "labyrinth" water outlet channel to quickly and accurately keep the skimmer in optimal condition.

Why Choose This Nano Skimmer

Unlike bulky traditional skimmers, this model is specifically optimized for 75-liter (20 Gallon) marine aquarium tanks. While standard filters may struggle with organic waste, this skimmer uses a professional-grade fine needle brush to strip proteins from the water before they break down. Its flexibility is unmatched; the ability to connect to a mobile power bank provides a critical lifeline for emergency oxygen and pollution discharge during unexpected power failures.
