What is SunSun HBL-803 Hang On Filter

SunSun HBL-803 Hang On Filter is a modern hang on aquarium filter that is mounted on the back or side glass of the aquarium. This type of filter is also known as hanging filters or HOB (Hang On Back) filters.

Their main advantage is that they combine compactness, efficiency and easy installation. The hang on aquarium filter draws water in through an inlet tube, passes it through the filter media, and returns it back to the aquarium in the form of a waterfall.

This process provides:

• mechanical filtration
• biological filtration
• additional aeration of the water

The SunSun HBL-803 is a popular hang on aquarium filter because it offers stable operation and good filtration efficiency in a relatively small size.

Advantages of the SunSun HBL-803 Hang On Filter

Compact design

One of the biggest advantages of this hang on aquarium filter is its compact design. The filter is placed outside the aquarium, which frees up internal space and improves the aesthetics of the aquarium.

This is especially important for:

• nano aquariums
• aquascaping systems
• aquariums with many plants

Quiet operation

The SunSun HBL-803 is designed for quiet and stable operation, making it suitable for aquariums in:

• living room
• office
• bedroom

Low noise level is an important factor when choosing a hang on filter for an aquarium, especially if the aquarium is located in a living room.

Efficient filtration

This hang on filter for an aquarium uses a combination of mechanical and biological filtration.

Mechanical filtration retains:

• food debris
• organic particles
• fine dirt

Biological filtration supports the development of beneficial bacteria that break down ammonia and nitrites.

For better biological stability, it is advisable to use quality biological filter media that increases the surface area for bacteria to develop.

How to choose a hang on filter for an aquarium

Choosing the right hang on filter for an aquarium depends on several important factors.

Aquarium size

The first criterion is the volume of the aquarium. The SunSun HBL-803 is suitable for:

• aquariums up to about 150 liters
• planted aquariums

The filter provides sufficient water circulation for a stable biological system.

Aquarium type

Hang on filters are very popular with:

• aquascape aquariums
• shrimp ponds
• nano systems

In small systems, a hang on aquarium filter is often used, which is mounted on the rear glass and provides good water circulation.

Filter media

A good hang on aquarium filter should allow the use of different filter media.

The combination of:

• sponge
• ceramics
• biological media

significantly improves the quality of filtration.

Suitable application
