Setting up a fish tank can feel overwhelming, especially when it comes to choosing the right filter. If you want clear water, a healthy environment, and happy fish, your filter choice matters.
A hang-on-back (HOB) filter might be exactly what you need. It’s easy to install, keeps your tank clean, and works quietly in the background. You’ll discover step-by-step how to set up your fish tank with a hang-on-back filter so your underwater world stays fresh and thriving.
Keep reading—you’re just moments away from making your fish tank care simpler and more effective.
Choosing The Right Fish Tank
Setting up a fish tank with a hang-on-back filter needs careful planning. Choosing the right tank is the first step for a healthy aquarium.
A good tank matches your space, fish types, and filter size. It helps your fish live happily and keeps the tank easy to manage.
Tank Size And Shape
Pick a tank size based on the fish you want to keep. Bigger tanks hold more water and give fish space to swim.
Shape matters too. A rectangular tank is best for most hang-on-back filters. It gives good water flow and fits well in rooms.
- Small tanks (5-10 gallons) are good for beginners.
- Medium tanks (20-30 gallons) suit many fish types.
- Large tanks (50+ gallons) need strong filters and more care.
- Rectangular shapes fit hang-on-back filters better than round ones.
Material Options
Fish tanks come in glass or acrylic. Both are clear but have different strengths and weaknesses.
Glass is heavy and scratch-resistant. Acrylic is lighter and easier to shape but can scratch more easily.
- Glass tanks are durable and cost-effective.
- Acrylic tanks are lighter and better for large sizes.
- Check the tank’s thickness to hold water safely.
- Choose a material that fits your budget and space.
Placement Tips
Place your tank on a strong, level surface. It should hold the tank’s full weight without wobbling.
Avoid direct sunlight. It can cause algae growth and temperature changes. Keep the tank away from heaters or air conditioners.
- Use a sturdy stand or table made for aquariums.
- Keep the tank near a power outlet for the filter.
- Leave space behind the tank for the hang-on-back filter.
- Place the tank where you can easily see and feed your fish.

Selecting A Hang-on-back Filter
Setting up a fish tank needs the right filter to keep water clean. Hang-on-back filters are easy to install and maintain. They hang on the back of the tank and work well for many fish tanks.
Choosing the right hang-on-back filter helps keep fish healthy and water clear. This guide covers filter types, flow rate, and top brands to help you decide.
Filter Types And Features
There are different hang-on-back filter types. Some use cartridges, others use sponges or bio-media. Each type cleans water in a special way.
- Cartridge Filters:Easy to replace and clean. Good for mechanical and chemical filtration.
- Sponge Filters:Great for biological filtration. Also gentle for small or delicate fish.
- Bio-Media Filters:Provide space for beneficial bacteria. Help break down fish waste naturally.
- Combination Filters:Use more than one filter type for better cleaning.
Flow Rate And Capacity
Flow rate means how much water the filter moves per hour. Capacity is the tank size the filter can handle. Both must match your fish tank needs.
| Tank Size (Gallons) | Recommended Flow Rate (GPH) |
|---|---|
| 10 or less | 100 – 150 |
| 10 to 30 | 150 – 300 |
| 30 to 50 | 300 – 500 |
| 50 and above | 500+ |
Choose a filter with a flow rate that cycles your tank water 4 to 5 times each hour. This keeps water clean without stressing fish.
Brand Recommendations
Some brands offer reliable hang-on-back filters with good parts and easy maintenance. Look for filters with good reviews and warranty.
- Brand A: Known for quiet operation and strong filters.
- Brand B: Offers filters with multiple media options.
- Brand C: Popular for energy efficiency and durability.
- Brand D: Good for beginner-friendly models and easy setup.
Preparing The Tank
Setting up a fish tank with a hang-on-back filter starts with proper preparation. A clean and well-arranged tank helps keep your fish healthy.
This guide covers cleaning the tank, adding substrate and decorations, and setting up plants for a great start.
Cleaning The Tank
Before adding water or fish, clean the tank carefully. Use warm water and a soft cloth or sponge.
Do not use soap or chemicals. These can harm your fish later. Rinse the tank well to remove any dust or dirt.
Adding Substrate And Decorations
Substrate is the material at the bottom of the tank. It helps plants grow and looks nice. Choose gravel or sand that suits your fish type.
Spread the substrate evenly, about 1 to 2 inches deep. Add decorations like rocks, caves, or driftwood for hiding places and beauty.
- Rinse substrate before adding to the tank
- Place decorations securely to avoid falling
- Keep open swimming space for fish
Setting Up Plants
Live plants improve water quality and give fish places to hide. Choose plants that grow well in your tank size and light.
Plant them gently into the substrate. Make sure roots are covered but leaves stay above the substrate. Trim dead leaves to keep plants healthy.

Installing The Hang-on-back Filter
Setting up a fish tank with a hang-on-back (HOB) filter helps keep the water clean. This filter type is easy to install and maintain.
Follow these steps to properly install and use your hang-on-back filter for the best results.
Mounting The Filter
Place the filter on the back edge of your fish tank. Make sure the filter hangs securely over the tank’s rim.
Check that the intake tube reaches near the bottom of the tank. This allows the filter to pull water efficiently.
- Clean the tank rim before mounting
- Hang the filter so it fits tightly
- Ensure the intake tube is submerged
Priming The Filter
Priming fills the filter with water to start the flow. Some filters prime automatically when plugged in.
If your filter does not prime automatically, pour water into the intake tube or priming hole. This helps start the pump.
- Fill the intake tube with water
- Use the priming button if available
- Check for water flow before plugging in
Adjusting Flow Settings
Most hang-on-back filters have flow control. Adjust the flow to fit your tank’s size and fish needs.
Turn the flow dial or lever to increase or decrease water flow. Avoid strong currents that stress fish.
- Start with medium flow
- Lower flow for small or delicate fish
- Higher flow for larger tanks or messy fish
- Observe fish behavior after adjustment
Cycling The Aquarium
Setting up a fish tank with a hang-on-back filter needs patience. Cycling the aquarium is a key step to create a healthy home for fish.
This process helps build good bacteria that clean the water. It can take a few weeks but keeps fish safe.
Nitrogen Cycle Basics
The nitrogen cycle breaks down fish waste and food leftovers. Good bacteria change harmful chemicals into safer ones.
First, ammonia forms from waste. Then bacteria turn ammonia into nitrites. Other bacteria change nitrites into nitrates, which are less harmful.
- Ammonia is toxic to fish
- Nitrites are still harmful but less than ammonia
- Nitrates are safer but need regular water changes
Monitoring Water Parameters
Testing water is important during cycling. It helps track ammonia, nitrite, and nitrate levels.
Use a water test kit to measure these chemicals. Keep a log to see changes over time.
- High ammonia means cycling is not complete
- Rising nitrites show bacteria growth
- When nitrites drop and nitrates rise, cycling is almost done
Tips For Faster Cycling
Some actions can speed up cycling. Adding filter media from a healthy tank helps good bacteria grow.
Keep the water warm and avoid strong cleaning. These steps support bacteria development.
- Add live plants to reduce ammonia
- Use a bacterial supplement if needed
- Feed fish lightly or use pure ammonia for fishless cycling
- Keep the filter running 24/7

Adding Fish And Maintenance
Setting up a fish tank is exciting. Ensuring the right environment is key for your fish’s health.
Using a hang-on-back filter helps keep the water clean. Let’s explore how to add fish and maintain the tank effectively.
Choosing Compatible Fish
Selecting the right fish is crucial. Fish must be compatible in size, behavior, and habitat needs.
- Research fish species for compatibility.
- Avoid aggressive species with peaceful ones.
- Ensure fish have similar temperature needs.
Feeding Guidelines
Proper feeding keeps fish healthy. Overfeeding can harm water quality.
| Fish Type | Feeding Frequency |
| Tropical Fish | Twice daily |
| Cold Water Fish | Once daily |
| Bottom Feeders | Every other day |
Routine Cleaning And Filter Care
Regular cleaning is needed for a healthy tank. Filters must be checked and maintained.
- Check filter for clogs
- Change 10-15% of the water
- Clean algae from tank walls
