10 Best Hang On Back Protein Skimmers 2025 in the United States

The Sicce Shark Nano Protein Skimmer is designed for small saltwater aquariums up to 40 gallons, making it a good fit for hobbyists with modestly sized tanks. One notable strength is its ultra-quiet pump, which ensures minimal noise disruption, an important factor for a pleasant aquarium setting. Its compact and discreet design helps it blend in seamlessly with the aquarium environment while the waterproof magnetic connection system offers flexibility in placement within the tank.

The skimmer also comes with a self-cleaning impeller and a cleaning brush included, which simplifies maintenance tasks, saving you time and effort. Additionally, the device has a solid build quality and comes with a 5-year manufacturer warranty, which speaks to its durability and reliability.

However, while the skimmer is efficient in protein diffusion and has a special large bottom surface suitable for breeding tanks or integration into internal filtration systems, it may not be ideal for larger tanks beyond 40 gallons. Some users might find the tank size compatibility limiting if they upgrade to a bigger setup. In conclusion, the Sicce Shark Nano Protein Skimmer is a well-rounded option for smaller tanks, delivering quiet operation and ease of maintenance, but it may not meet the needs of larger aquarium enthusiasts.

The Reef Octopus OCTO Classic 1000 HOB Protein Skimmer Bundle is a robust option for aquarium enthusiasts, particularly those with tanks up to 130 gallons. Its ability to cater to different bio loads (light, medium, heavy) makes it versatile. The skimmer features a low-profile body and a powerful Reef Octopus Aquatrance 1000s Pinwheel Pump, known for its efficient and low-heat performance. The external pump installation also aids in easy setup and operation.

Additionally, the air silencer and solid acrylic construction contribute to a quieter and more durable product, beneficial for maintaining a peaceful aquarium environment. The bundle includes useful extras like a MarineAndReef Reefractometer, ideal for accurate salinity readings, and a durable, lint-free microfiber towel for cleaning tasks.

Some drawbacks include the noise level, which could still be a concern despite the air silencer, and maintenance might require a bit of effort due to the external pump. Also, the build quality is reliable, though the product's modern style and plastic material may not appeal to everyone. This bundle is highly recommended for dedicated aquarium keepers who prioritize effective protein skimming and value-added accessories.

The Reef Octopus BH90 Hang on Protein Skimmer is designed for aquarium enthusiasts looking for an effective way to maintain water quality. With its compatibility for tanks up to 90 gallons, it’s suitable for both novice and experienced aquarists. One of its strong points is its efficient pump power, which helps in producing a good amount of bubbles for effective protein skimming. This results in cleaner water, which is essential for the health of your aquatic pets. Additionally, the skimmer is made from stainless steel and offers solid build quality, contributing to its durability and reliability.

Ease of maintenance is another plus; the skimmer is designed to be user-friendly, allowing for straightforward cleaning and part replacement when necessary. The fact that it's dishwasher safe is a nice touch, making upkeep even more convenient. However, there are some aspects to consider. While the noise level is generally acceptable, it may be a bit louder than some users would prefer, particularly in quieter home environments.

Its size, at 17.9 x 17.9 x 12 inches, means it requires adequate space on the tank's rim, which could be a drawback for smaller setups. Some users have reported that while the skimmer performs adequately, it may not handle the highest bioloads as effectively as larger models, potentially leaving some users wanting more skimming power.
