Nano DC Protein Skimmer NSK-70 with DC Flow Controllable Pump (2nd Gen) – Fiji Cube

Fiji Cube 2nd Gen NSK-70 is a powerhouse of filtration designed specifically for space-constrained nano and AIO (All-In-One) aquariums. Combining a compact footprint with the advanced control of a DC-powered pump, this skimmer provides the professional-grade organic removal typically reserved for much larger systems.

Key Features & Benefits

• DC Flow Controllable Pump:Unlike traditional AC skimmers, the NSK-70 features a high-efficiency DC pump. This allows you to fine-tune the water flow and air intake directly via the controller, ensuring a perfect “sweet spot” for foam production regardless of your bio-load.
• Integrated Needle Wheel Impeller:The specialized impeller shreds air into a dense “milk” of micro-bubbles, maximizing the surface area for organic waste attachment.
• Space-Saving Design:Engineered with a tiny footprint, it fits easily into the rear filtration chambers of most popular nano tanks (like Fiji Cube, Innovative Marine, or Waterbox systems).
• Quiet Operation:The DC motor technology significantly reduces vibration and humming, making it one of the quietest skimmers in its class—perfect for office or bedroom setups.
• Adjustable Water Level:The easy-turn adjustment pipe allows for precise control over the internal water level, giving you the choice between “dry” or “wet” skimming.

Technical Specifications

What’s Included?

1. NSK-70 Protein Skimmer Bodywith high-clarity acrylic.
2. DC Needle Wheel Pumpfor optimal bubble production.
3. Digital Controllerfor flow adjustment and “Feed Mode” pausing.
4. Collection Cupwith an easy-removal lid for maintenance.

Why Choose the 2nd Gen?

The second generation of the NSK series focuses ondurability and ease of maintenance. The updated pump bracket and refined body geometry prevent turbulence, leading to a faster “break-in” period and more consistent skimmate production compared to the original model.
