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 adjustable surface skimmer attachment adds flexibility, allowing for better customization based on specific tank needs. The skimmer's build quality is robust, made from durable acrylic, which ensures longevity and reliability. However, its 21-inch height and 4-inch width may require some consideration for installation space.

While not overly complicated, maintenance can be a bit time-consuming, as it is not dishwasher safe and needs regular manual cleaning. Noise levels are moderate, typical for skimmers of this type, but may not be suitable for those seeking a completely quiet aquarium setup. The OCTO Classic BH-2000 is a solid choice for hobbyists with larger tanks who value effective protein removal and durability, though they should be prepared for regular maintenance and some noise.

Its build quality, made from polypropylene, ensures durability, though it may not be as premium as some higher-end models made from acrylic. The ease of maintenance is facilitated by its design, but some users might find it slightly challenging due to its compactness and the need to maintain the recommended sump water height of 7-8 inches.

Noise levels are relatively low, making it suitable for quieter environments. However, it might not be entirely silent for those extremely sensitive to operational sounds. This protein skimmer is ideal for fish enthusiasts who need a reliable and efficient skimmer for mid-sized aquariums up to 160 gallons and prefer a product that balances performance and space efficiency.
