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 OCTO Classic BH-2000 Protein Skimmer is designed for aquariums up to 208 gallons, making it suitable for medium to large tanks. This hang-on skimmer features an Aquatrance 2000 Pinwheel pump, known for its efficient air intake and water flow rate, which helps in maintaining water quality by removing proteins and organic compounds effectively.

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.

The Simplicity 320DC Protein Skimmer is designed for aquarium tanks up to 320 gallons, making it a good choice for medium to large reef tanks. It uses an adjustable DC pump, which allows you to control the water flow and air intake to optimize skimming performance depending on your tank's needs. Its cone-shaped design and compact footprint help save space inside the aquarium setup.

The collection cup features a drain with a cap, which simplifies maintenance by making it easier to empty without removing the entire cup. The skimmer is submersible and made with solid materials, giving it a sturdy feel at 11 pounds. Users generally find it quiet during operation, which is a plus for home or office environments. However, some might find the absence of a lid on the collection cup a minor downside, as it can potentially allow odors to escape.

The adjustable pump speed is convenient but requires some trial and error to find the best setting. This skimmer effectively balances performance and ease of use, making it a reliable option for fish and reef enthusiasts wanting a compact, effective protein skimmer without complex setup.
