SunSun YBF-500

SunSun YBF-500 Hang-On Canister Filter

The SunSun YBF-500 is a compact Hang-On Canister Filter that combines the convenience of a HOB filter with a larger, multi-stage filtration system. With a 500 L/H flow rate and only 6W of power consumption, it is designed for planted aquariums, aquascapes and freshwater setups where efficient filtration is required without taking up valuable space inside the aquarium.

The YBF-500 features adjustable water flow, surface oil-film removal, fish-waste separation and multiple filtration chambers, allowing you to customize the filtration according to your aquarium's needs.

Multi-Stage Filtration

Unlike a basic HOB filter that relies primarily on a single filter compartment, the YBF-500 provides multiple filtration sections where different types of media can be arranged according to your setup.

Mechanical Filtration

Mechanical media captures suspended particles, uneaten food, plant debris and other visible impurities from the water column.

Biological Filtration

The available media space can be used with biological media such as ceramic rings or other porous media, providing additional surface area for beneficial bacteria.

Chemical Filtration

When required, the filter can also accommodate suitable chemical media such as activated carbon or other specialized filtration media.

This flexible media arrangement allows the YBF-500 to be configured differently depending on the aquarium and its filtration requirements.

Adjustable Water Flow

The YBF-500 includes a flow-control mechanism, allowing you to regulate the water movement according to your aquarium.

This is particularly useful for planted aquariums and livestock that may not appreciate excessively strong circulation.

Built-In Surface Oil-Film Removal

The YBF-500 incorporates a surface intake designed to help remove oil film and floating surface debris.

Keeping the water surface cleaner can improve surface gas exchange while also maintaining a clearer, cleaner appearance in the aquarium.

Fish-Waste Separation

A dedicated fish-waste separation system helps collect larger waste particles before they unnecessarily accumulate throughout the main filter media.

This design can make routine maintenance more convenient and help maintain consistent filtration performance.

Water Injection & Maintenance

The YBF-500 includes a dedicated water-injection opening, making it easier to replenish water inside the filter during setup or when required.

Its external HOB configuration also makes accessing the filtration compartments straightforward for routine cleaning and media maintenance.

Suitable For

The YBF-500 is well suited for:

• Planted aquariums
• Aquascaping setups
• Community freshwater aquariums
• Shrimp setups
• Small to medium freshwater tanks
• Aquariums approximately 40–80 cm in length

The actual suitable water volume depends on livestock load, aquascape density, filter-media configuration and the desired turnover rate. Some current listings describe the YBF-500 as suitable for tanks up to approximately 100–130L, so tank dimensions and stocking should be considered rather than relying on a single litre figure.

Compact External Design

The YBF-500 hangs on the rear of the aquarium, keeping the main filter body outside the tank.

This provides more usable space inside the aquarium while keeping the aquascape visually cleaner and making filter maintenance easier.

Its 185 × 90 × 255 mm body makes it the more compact option in the YBF series compared with the YBF-600.

Low Power Consumption

With a power consumption of only 6W, the YBF-500 provides a maximum rated flow of 500 L/H while keeping electrical consumption relatively low.

This makes it a practical choice for aquarists looking for continuous filtration without using a high-powered filter.

Installation & Maintenance

Mount the filter securely onto the rear glass of the aquarium, ensuring that the aquarium glass is within the supported 12 mm maximum thickness.

Before powering on the filter, make sure the filter body and pump are properly filled with water. Never operate the pump dry.

For routine maintenance:

• Clean mechanical filter media when flow begins to decrease.
• Remove accumulated debris from the waste-separation section regularly.
• Rinse biological media gently using removed aquarium water.
• Inspect and clean the impeller periodically to maintain proper flow.
• Check the intake and surface skimmer for plant debris or other blockages.

Why Choose the YBF-500?

The SunSun YBF-500 offers a practical balance between compact size, filtration capacity and power efficiency.

With 500 L/H flow, 6W power consumption, adjustable flow, multi-stage filtration, surface oil-film removal and waste separation, it provides considerably more flexibility than a basic single-compartment HOB filter while retaining the easy installation and maintenance of a hang-on design.

A compact filtration solution for aquascapers and freshwater hobbyists who want more filtration flexibility without placing a bulky filter inside the aquarium.
