Professional Filtration Engineered for Every Aquarist
Whether you are setting up your first nano tank or managing a vibrant planted aquarium, clean and well-oxygenated water is the foundation of fish health.
TheAQUASMITH Hang-On-Back (HOB) Filter combines commercial-grade filtration principles with user-friendly convenience, solving the most common frustrations of traditional aquarium filters.
Key Features & Innovations:
Dual-Layer Wet/Dry Separation:
Traditional filters let fish waste and uneaten food sit submerged in water, constantly breaking down into harmful ammonia and nitrates. Our innovative wet/dry drawer isolates solid waste from the water stream, preventing organic decomposition before it pollutes your tank.
Trickle Rain-Spray Oxygenation:
The rain-pipe distribution system evenly sprinkles water over the biological media, drastically increasing gas exchange and dissolved oxygen (DO). This creates an optimal breeding ground for beneficial nitrifying bacteria.
Independent Bio-Chamber & 4–5X Turnover:
Designed to turn over aquarium water 4 to 5 times per hour, meeting true hobbyist standards. The dedicated biological chamber comes equipped with premium bio-media and fully supports customizable filtration media.
Cut-to-Fit Universal Media Design:
Stop wasting money on overpriced branded filter cartridges. Simply trim universal filter floss to fit. When it’s time to clean, slide out the mechanical tray without tearing down your biological filtration or unplugging the entire unit.
Auto-Leveling Surface Skimmer: Continuously skims the surface to remove stubborn bio-films, organic oils, dust, and floating plant fragments, ensuring sparkling water clarity from every angle.
Choosing the Right Model for Your Aquarium:
Model 79 GPH:
Ideal for 10–20 Gallon rimless tanks
Model 132 GPH:
Ideal for 20–35 Gallon rimless tanks
Tank Compatibility:
Fits rimless glass aquariums with a rim thickness up to 10 mm (0.4 inches)
Worry-Free Support & AQUASMITH Guarantee:

. If you ever need replacement parts, setup guidance, or troubleshooting assistance, simply contact our support team via the manual instructions or customer support email.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $2 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for AQUASMITH products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
