What Are Hang-on-back Filters
Hang-On-Back filters, often called HOB filters, are popular aquarium filters. They hang on the back wall of a fish tank. These filters help keep aquarium water clean and healthy.
HOB filters work by pulling water from the tank, filtering it, and then returning clean water back. They are easy to install and use.
Basic Design And Function
A Hang-On-Back filter has a simple design that fits many tank sizes. It uses a motor to draw water from the aquarium. The water passes through filter media inside the unit. Then, the clean water flows back into the tank.
- Water intake tube pulls water from the aquarium.
- Filter media removes dirt and waste.
- Motor powers water flow.
- Clean water returns to the tank.
Common Components
Hang-On-Back filters share several key parts. Each part plays a role in cleaning aquarium water.
| Component | Purpose |
|---|---|
| Water Intake Tube | Draws water from the aquarium into the filter. |
| Filter Media | Traps debris and removes impurities. |
| Impeller or Motor | Moves water through the filter system. |
| Outflow Spout | Returns clean water to the aquarium. |
| Filter Housing | Holds all parts together and hangs on tank. |

Benefits Of Using Hob Filters
Hang-On-Back (HOB) filters are popular for home aquariums. They hang on the tank’s back wall and help keep water clean.
These filters offer several benefits that make aquarium care easier and more effective.
Space Efficiency
HOB filters save space inside the aquarium. They hang outside the tank, so they do not take room away from fish or decorations.
This design works well for small tanks or crowded setups. It keeps the aquarium neat and open.
Ease Of Maintenance
HOB filters are easy to access for cleaning and filter changes. You can quickly remove the filter from the tank without disturbing fish.
Cleaning these filters takes less time compared to some built-in filters. This makes regular maintenance simple.
- Quick to remove and clean
- Simple to replace filter media
- Minimal tank disturbance
Effective Filtration
HOB filters provide mechanical, chemical, and biological filtration. They trap debris, remove toxins, and support beneficial bacteria.
This multi-stage filtration helps keep water clear and healthy for fish. The filter media can be customized to fit your tank’s needs.
Types Of Filtration In Hob Filters
Hang-On-Back (HOB) filters clean aquarium water in three main ways. Each type of filtration helps keep fish healthy and water clear.
These filters fit on the back of the tank and use different materials to remove waste and toxins from the water.
Mechanical Filtration
Mechanical filtration traps solid particles like uneaten food and fish waste. It stops these particles from floating in the water.
The filter uses sponges or pads that catch debris as water flows through them. These materials must be cleaned often.
- Removes visible dirt and particles
- Prevents water cloudiness
- Protects other filter parts from clogging
Biological Filtration
Biological filtration uses good bacteria to break down harmful waste. These bacteria live on filter surfaces and turn waste into less harmful substances.
This process helps keep ammonia and nitrite levels safe for fish. It is important for a healthy aquarium environment.
- Breaks down toxic ammonia and nitrites
- Supports beneficial bacteria growth
- Improves water quality naturally
Chemical Filtration
Chemical filtration removes dissolved chemicals and odors from water. It uses materials like activated carbon or resins to absorb impurities.
This filtration type helps clear water and remove smells. It also removes some toxins that mechanical and biological filters cannot catch.
- Absorbs harmful chemicals and toxins
- Removes odors and discoloration
- Improves water clarity and safety
Choosing The Right Hob Filter
Hang-On-Back (HOB) filters are popular for keeping aquarium water clean. Picking the right filter helps maintain a healthy tank environment.
Different tanks need different filter sizes and types. Knowing what to look for makes choosing easier.
Tank Size Compatibility
Each HOB filter is designed for a specific tank size range. Choosing one that fits your tank ensures proper filtration.
Using a filter too small or too large can cause problems like weak cleaning or waste of energy.
- Check the filter label for recommended tank size
- Match the filter capacity to your aquarium’s gallons
- Consider future tank upgrades when choosing size
Flow Rate Considerations
Flow rate is how much water the filter moves per hour. It affects water cleanliness and fish comfort.
Choose a flow rate that cleans well but does not stress your fish with strong currents.
- Look for filters with adjustable flow rates
- Higher flow rates suit heavily stocked tanks
- Lower flow rates work better for delicate fish
Filter Media Options
Filter media remove debris, chemicals, and waste from the water. Different media types serve different purposes.
Choosing the right media helps keep water clear and safe for fish and plants.
- Mechanical media traps particles and dirt
- Chemical media removes odors and toxins
- Biological media supports good bacteria growth

- Check that water flows smoothly through the filter.
Positioning For Optimal Flow
Correct positioning improves water circulation and filtration. Place your filter where water moves well but does not disturb fish too much.
| Position | Benefit |
| Center of tank back wall | Even water flow across the tank |
| Near plants or decorations | Prevents debris buildup in corners |
| Avoid direct water spray on fish | Reduces fish stress |
