Reef Octopus Regal 250EXT Protein Skimmer for Aquariums

The Reef Octopus Regal 250-EXT Protein Skimmer, a powerful, high-performance, recirculating skimmer designed for large saltwater aquariums (up to 2271 litres). It features a large 250mm diameter body, uses a Reef Octopus VarioS DC skimmer pump for precise control over air and water flow, and is made from high-quality cast acrylic. The "pin-wheel" likely refers to the type of pump impeller used in the VarioS pump. 

Features:

• Controllable VarioS DC Pump: The skimmer is equipped with a specific VarioS-6S DC pinwheel pump that allows for precise control of water and air flow through five speed settings.
• External/Recirculating Design: The dual-pump, external (out-of-sump) configuration ensures stable performance unaffected by sump water levels, processes water multiple times, and maximizes bubble contact time for more efficient organic waste removal.
• High-Quality Construction: The body is hand-made from robust, solid cast acrylic, which is durable and designed for easy disassembly for maintenance and cleaning.
• Hybrid Conical Body: This design naturally stabilizes and concentrates the organic-rich foam as it rises, improving foam fractionation.
• Advanced Control Options:
• Feed Mode: A push button engages a 15- or 60-minute pause for feeding or maintenance.
• Float Switch: Includes a built-in float switch connection that automatically shuts off the pump if the collection cup is full, preventing overflow.
• 3rd Party Controller Integration: A 0-10V input port allows the skimmer to be controlled by external aquarium controllers like Neptune Systems' APEX.
• Quiet and Energy Efficient: The VarioS DC pump is known for its silent operation and high energy efficiency compared to traditional AC pumps. 

Benefits:

• Superior Water Quality: The primary benefit is the removal of dissolved organic compounds (DOCs) before they break down into harmful nitrates and phosphates, which helps maintain stable water parameters and a healthier environment for fish and corals.
• Reduced Algae Growth: By exporting nutrients that fuel nuisance algae, the skimmer helps control algae outbreaks, leading to a cleaner tank and less manual cleaning.
• Enhanced Oxygenation: The vigorous mixing of air and water promotes excellent gas exchange, increasing dissolved oxygen levels in the aquarium, which is vital for marine life health.
• Improved Water Clarity: The removal of pigments and fine organic particles results in crystal clear water, improving light penetration and the overall visual appeal of the aquarium.
• Ease of Tuning and Maintenance: The independent control over water flow (via a separate feed pump) and air draw (via the VarioS controller) makes the skimmer easier to "dial in" for optimal performance, while the external placement simplifies general maintenance

How it works

1.     The recirculating system draws air and water into the skimmer body using separate pumps.

2.     The internal pin-wheel pump creates a mixture of fine bubbles, which rise through the skimmer body.

3.     As the bubbles rise, they attract and collect organic waste from the water.

4.     The foam concentrates in the collection cup at the top, where it can be easily removed.

5.     The external pump manages the flow and contact time, which can be precisely controlled with the pump's settings and the skimmer's outlet valve.
