The OCTO Classic 2000-HOB Protein Skimmer, manufactured by Reef Octopus, is a popular choice in the hang-on-back protein skimmer category. It is designed for use with a range of tank sizes, making it versatile for different aquarium setups. The skimmer features a powerful pump that ensures effective bubble production, which is essential for removing organic waste from the water. This makes it a good fit for maintaining a clean and healthy aquatic environment.

Additionally, the build quality is robust, as expected from a reputable brand like Reef Octopus. The materials used are durable, ensuring that the skimmer can withstand regular use over time. One of the notable strengths of this skimmer is its ease of maintenance. The design allows for easy disassembly, making it straightforward to clean and maintain. This is particularly beneficial for aquarium owners who want to ensure their equipment is running efficiently without too much hassle.

However, there are a few drawbacks to consider. Some users have reported that the skimmer can be relatively noisy, which might be a concern if your aquarium is located in a quiet living space. Additionally, while the product is not discontinued, it has been available on the market since 2014, meaning there may be newer models with more advanced features available. In summary, the OCTO Classic 2000-HOB Protein Skimmer is a reliable and effective choice for aquarium enthusiasts, offering strong performance and ease of maintenance, though potential noise levels and the availability of newer models might be considerations to keep in mind.

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 OCTO Classic BH-2000 Protein Skimmer is designed for aquariums up to 208 gallons, making it a solid choice for medium to large setups.

Users appreciate the adjustable surface skimmer attachment, allowing for better customization based on their tank's needs.

In terms of maintenance, many find the unit relatively easy to clean, which is often a significant concern for aquarium owners. The build quality, made from acrylic, feels sturdy, contributing to its longevity. Noise levels are generally manageable, although some users might find it slightly louder than desired, especially in quieter environments.

A notable drawback is the size; with a footprint of 10" x 4" and a height of 21", it may require careful consideration of tank setup space. For those looking for a reliable hang-on-back protein skimmer, the OCTO Classic BH-2000 is suitable for both novice and experienced aquarium keepers, offering good performance with attention to maintenance. Potential buyers should ensure they have sufficient space for installation and be prepared for some noise, depending on their specific environment.
