10 Best Protein Skimmers 2025 in the United States

The Reef Octopus OCTO Regal 150-INT In-Sump Protein Skimmer is designed for aquarists who are looking for an efficient way to maintain water quality in medium to large tanks, accommodating up to 210 gallons with light filtration demands. A standout feature is its small footprint, making it suitable for setups with limited space, and the DC controllable pump allows for energy-efficient operation tailored to your aquarium's needs.

One of the strengths of the OCTO Regal is its build quality. Made from durable materials like acrylic and foam, it promises longevity and effectiveness. The adjustable pump with five energy-efficient power settings is a plus, as it gives users flexibility in managing the skimmer's operation based on specific tank requirements.

However, there are some considerations to keep in mind. While the skimmer excels in many areas, it might not perform as efficiently at its maximum rated tank size under heavy filtration demands, particularly for aquariums up to 100 gallons. This could be a drawback for users with larger bioloads. Additionally, the recommended sump water depth of 6-8 inches may limit compatibility with some setups, and maintenance may require regular cleaning due to its design. Noise level is generally acceptable, but some users might still find it a bit noticeable, especially in quieter environments. If you're looking for a reliable protein skimmer for a medium to large aquarium that requires manageable noise levels and efficient filtration without taking up much space, the Reef Octopus OCTO Regal 150-INT could be a strong contender. Just ensure your tank setup aligns with its specifications for optimal performance.
