Review REEF OCTOPUS Regal Internal Protein Skimmer Pump Marine 2800l/740g
The **Reef Octopus 300-INT Regal Internal Protein Skimmer** is a high-performance, space-efficient solution designed to elevate the clarity and health of your marine aquarium, particularly suited for systems ranging from 2,800 liters (740 gallons) up to 5,600 liters (1,500 gallons). Engineered with precision, this internal skimmer integrates seamlessly into your tank setup, eliminating the need for bulky external units while delivering the same exceptional protein removal capabilities. Its compact yet robust design features a **300mm (12-inch) foam fractionator**, optimized for maximum surface area to efficiently trap and eliminate organic waste, fine particulates, and excess nutrients before they contribute to algae blooms or degrade water quality. The **5,500-liter-per-hour (2800L/740G) high-capacity pump** ensures relentless airflow and water circulation, driving the skimmer s core mechanism with consistent power to maintain optimal performance even in large-scale systems. Built with marine-grade materials, the Regal s internal housing is constructed from durable, corrosion-resistant components, ensuring longevity and reliability in saltwater environments. The skimmer s modular design allows for easy maintenance, with quick-access components for cleaning the foam fractionator, collecting the skimmate, and servicing the pump without disrupting the aquarium s ecosystem. Whether integrated into a sophisticated reef tank, a large-scale display system, or a high-bioload community setup, this skimmer excels in reducing cloudiness, minimizing manual water changes, and promoting crystal-clear water by targeting the root causes of water degradation. Ideal for aquarists seeking a streamlined yet powerful solution, the Reef Octopus 300-INT Regal Internal Protein Skimmer combines efficiency, durability, and ease of use to help maintain pristine water conditions with minimal effort.

However, the high cost and occasional maintenance demands may be drawbacks for smaller systems or budget-conscious hobbyists.
For **large reef tanks (2000L )** with high bioloads, this skimmer is highly recommended. For smaller setups or those seeking more customization, a smaller or external skimmer might be a better fit.
### **Recommendation**
If you have a **large reef tank (2000L 3000L range)** and prioritize efficiency, durability, and ease of maintenance, this skimmer is a strong investment. Ensure your system has sufficient space and a stable power supply. If you re working with a smaller tank or need more flexibility, consider a smaller internal skimmer or an external model instead.
