10 Best Protein Skimmers 2026 in the United States

The Reef Octopus OCTO Regal 150 SSS Space Saver Protein Skimmer is designed for aquariums of varying sizes, making it versatile for a range of tank setups. It is effective for tanks up to 210 gallons with light filtration needs, 160 gallons with medium filtration demands, and 100 gallons for high filtration requirements. This makes it suitable for both moderate and heavily stocked aquariums. Its small footprint (9” x 7.5”) and height (23.6”) ensure it doesn't take up much space, which is beneficial for users with limited sump space.

The skimmer is equipped with a controllable DC 2500S Pinwheel Pump, offering five energy-efficient power settings, allowing for customizable performance and potentially lower electricity costs. The build quality leverages modern materials and is designed to last, although it is primarily plastic, which might be a consideration for some users seeking more robust materials. Maintenance is another advantage, with a recommended sump water depth of 7” to 8.5” making it relatively easy to access and clean. However, it is essential to note that the product is not dishwasher safe, so manual cleaning is required.

In terms of noise, the controllable DC pump is generally quieter compared to traditional AC pumps, contributing to a more peaceful aquarium environment. The skimmer includes adapters for different plumbing setups, adding to its versatility. While customer reviews are highly positive, reflecting satisfaction with performance and build, the relatively high weight (12.47 pounds) might be a minor drawback for some users during installation or maintenance. In summary, the Reef Octopus OCTO Regal 150 SSS is a reliable and efficient protein skimmer that suits a variety of aquarium sizes, with ease of maintenance and noise levels being significant strengths. Potential users should consider the material and weight aspects based on their specific needs and preferences.

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.

It is engineered for near-silent operation, which is a big plus if your aquarium is in a living space where noise matters.
