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.
