Reef Octopus Regal 170EXT Protein Skimmer for Aquariums

The Reef Octopus Regal-170EXT Skimmer offers precise control and efficient filtration, primarily due to its advanced controllable DC pump and robust, easy-to-maintain design. 

Features & Benefits:

• Controllable DC Pump: Equipped with a variable speed RO-DC 3500s (or VarioS) pinwheel pump, the user can electronically control air and water flow rates via five preset speeds on a detachable controller.
• External (Recirculating) Design: The pump is mounted outside the main body, allowing water to recirculate within the skimmer body for increased contact time and superior performance, while also simplifying pump access for maintenance.
• High-Quality Construction: The skimmer is built with solid, hand-made cast acrylic and can be completely disassembled for thorough cleaning.
• Hybrid Conical Body: The body design naturally stabilizes and concentrates the organic-rich foam as it rises, improving foam fractionation and waste removal efficiency.
• Enhanced Control Features: The controller includes a 10-minute feed/service mode to temporarily shut off the skimmer during feeding and a slow startup feature that gradually ramps up the pump speed. It also has a float switch monitor to prevent the collection cup from overflowing.
• Quiet and Energy Efficient: The DC pump technology ensures a quiet operation and is more energy-efficient than traditional AC pumps. 

• Superior Nutrient Export: The primary benefit is efficient removal of dissolved organic compounds (fish waste, uneaten food, etc.) before they break down into harmful nitrates and phosphates, which is a key method of nutrient export in saltwater aquariums.
• Stable Water Parameters: By consistently removing waste, the skimmer helps maintain stable water chemistry, a crucial factor for the health of sensitive corals and fish.
• Improved Water Clarity and Light Penetration: Removing coloring pigments and other organics results in crystal clear water, which not only looks better but also allows maximum light penetration for corals.
• Reduced Algae Growth: By stripping the water of excess nutrients that fuel algae, the skimmer helps control nuisance algae outbreaks.
• Enhanced Oxygenation: The creation of fine microbubbles increases the surface area for gas exchange, boosting oxygen levels in the water and helping to maintain a stable pH.
• User Flexibility and Control: The adjustable DC pump allows the user to fine-tune the skimmer's performance to match the tank's specific bioload (light, medium, or heavy) and adapt to changing conditions, a significant advantage over non-controllable AC skimmers.
• Long-lasting and Reliable: The high-quality ceramic shaft and bearing in the pump, combined with robust acrylic construction, contribute to a long lifespan and proven reliability, making it a "gold standard" in the hobby.
