Featuring a **large foam fractionator chamber**, the BH-100 maximizes surface area for optimal protein removal, reducing the risk of nutrient-driven algae outbreaks and promoting a cleaner, more stable ecosystem. Its **low-maintenance design** includes a removable collection cup for easy waste disposal, while the integrated **water flow diverter** ensures smooth operation with minimal energy consumption. Whether placed in a dedicated sump or mounted directly on the tank, this skimmer s **space-saving hang-on configuration** makes it a versatile upgrade for both new and experienced reef keepers aiming to elevate water clarity and biological balance in their 90-gallon systems. Built with reliability in mind, the Reef Octopus BH-100 combines cutting-edge filtration technology with user-friendly functionality, making it a standout choice for maintaining a thriving, low-stress marine environment.

### **Pros and Cons of buying a Reef Octopus BH-100 Octo Classic Hang Protein Skimmer for a 90-Gallon System**

#### **Pros:**

1. **Effective Protein Skimming** The BH-100 is designed to handle mid-sized systems (up to 100 gallons), making it suitable for a 90-gallon reef tank. Protein skimmers are essential for maintaining water quality by removing organic waste, reducing nutrient levels, and preventing algae outbreaks.

2. **Durable Construction** The skimmer is built with high-quality materials, including a reinforced PVC body and a durable motor. This suggests longevity and resistance to wear from saltwater exposure.

3. **Adjustable Airflow and Water Flow** The adjustable airflow and water flow settings allow for customization based on tank conditions. Proper tuning can optimize skimming efficiency and reduce foam overflow.

4. **Easy Installation** The hang-on design simplifies setup, as it can be mounted on the side of the tank without requiring a separate stand or complex plumbing. This makes it a convenient choice for aquarists who prefer minimal modifications to their setup.

5. **Good for Reef Tanks** Since it s marketed as an "Octo Classic" for reef systems, it likely includes features beneficial for corals and invertebrates, such as low turbulence and efficient waste removal.

6. **Affordable Compared to Larger Skimmers** For a 90-gallon system, this skimmer strikes a balance between performance and cost, avoiding the expense of oversized units while still providing adequate skimming capacity.

7. **Low Maintenance** Protein skimmers generally require minimal upkeep, primarily involving occasional cleaning of the foam fractionator and checking water flow. The BH-100 appears to follow this trend, making it user-friendly.

---

#### **Cons:**

1. **Size Limitations** While it s rated for up to 100 gallons, a 90-gallon tank may still require fine-tuning to ensure optimal performance. If the tank has high organic load (e.g., heavy feeding or many large fish), the skimmer might struggle without additional adjustments.

2. **Potential for Overfoaming** Some hang-on skimmers can produce excessive foam if not properly calibrated, leading to wasted water and potential clogging. This requires careful monitoring and occasional cleaning of the foam fractionator.

3. **Dependence on Air Pump** The skimmer relies on an external air pump for airflow. If the pump fails or loses pressure, the skimmer s efficiency will drop, potentially leading to poor water quality.

4. **Limited Customization for Advanced Users** Unlike some high-end skimmers, the BH-100 may lack advanced features such as variable speed controls or modular components, which could be desirable for aquarists seeking fine-tuned performance.

5. **Placement Constraints** As a hang-on model, it must be mounted near the tank s surface, which may not always be aesthetically pleasing or practical in densely arranged setups. It also requires a stable surface to prevent leaks or dislodging.

6. **Potential for Clogging** Organic debris or fine particles can accumulate in the skimmer s internal components, requiring regular cleaning. Neglecting maintenance can lead to reduced efficiency or even system failure.

7. **Noise Level** Some hang-on skimmers produce noticeable noise from the air pump and water flow, which may be disruptive in quiet environments.

### **Conclusion and Recommendation**

The **Reef Octopus BH-100 Octo Classic Hang Protein Skimmer** is a solid choice for a **90-gallon reef tank**, particularly for aquarists who prioritize simplicity, durability, and effective protein removal without investing in a high-end system. Its hang-on design makes installation straightforward, and its mid-range capacity ensures it can handle the organic load of a moderately stocked reef tank.

**Recommendation:**

- **Buy it if:** You need a reliable, low-maintenance skimmer for a 90-gallon reef system and prefer a hang-on model. It s a good balance of performance and affordability, especially for beginners or intermediate aquarists.

- **Consider alternatives if:** Your tank has very high organic output (e.g., heavy feeding, many large fish, or a high-density coral setup), in which case a slightly larger skimmer (e.g., 120-gallon rated) or a different model with more adjustable features might be better. Additionally, if noise or aesthetics are concerns, a submersible skimmer or a more compact hang-on model could be preferable.

**Final Verdict:** The BH-100 is a **recommended purchase** for most 90-gallon reef tanks, provided you are willing to monitor and adjust it for optimal performance. Pair it with a quality air pump and regular maintenance to ensure long-term reliability.
