These filters hold a lot of media for mechanical, chemical, and biological cleaning. They work well for larger tanks.
- Powerful filtration with large media capacity
- Quiet operation
- Easy to customize media types
- Needs more space outside the tank
Hang-on-back Filters
Hang-on-back filters hang on the tank edge. Water flows up, through filter media, then back into the tank.
They are simple to install and good for small to medium tanks. They offer mechanical, chemical, and biological filtration.
- Easy to install and maintain
- Suitable for small to medium tanks
- Compact design saves space
- May cause some water splashing
Sponge Filters
Sponge filters use air bubbles to push water through a sponge. They provide gentle and efficient biological filtration.
These filters are safe for small or delicate fish. They do not create strong currents and are easy to clean.
- Gentle water flow, good for fry and shrimp
- Easy to clean and reuse
- Cost-effective and simple
- Less effective for large tanks
Internal Filters
Internal filters sit inside the tank. They use a motor to pull water through filter media inside the unit.
These filters are good for small tanks or species that like hiding places. They usually combine mechanical and biological filtration.
- Compact and placed inside the tank
- Good for small or planted tanks
- Easy to install and maintain
- Can take up space inside the tank

Choosing The Right Filter
Choosing the right filtration system is important for a healthy species tank. The filter keeps water clean and safe for fish.
Filters remove waste, debris, and harmful chemicals. Picking the right one depends on several factors.
Tank Size And Stocking Levels
Tank size affects the filter type and size you need. Bigger tanks need stronger filters to clean all the water.
Stocking levels mean how many fish or animals live in the tank. More animals produce more waste, needing better filtration.
- Small tanks (under 20 gallons) can use smaller internal filters
- Medium tanks (20 to 50 gallons) need medium power filters
- Large tanks (over 50 gallons) require powerful external filters
- High stocking needs filters with higher capacity
Filter Flow Rate
The flow rate shows how much water the filter moves each hour. It is measured in gallons per hour (GPH).
Choose a flow rate that cleans the tank water at least 4 to 5 times per hour. Too strong flow can stress fish.
- Calculate tank volume in gallons
- Multiply by 4 or 5 to get needed GPH
- Pick a filter close to this flow rate
- Adjust flow if fish prefer calmer water
Ease Of Maintenance
Filters need regular cleaning to work well. Easy maintenance means less work and better tank health.
Look for filters with simple parts that you can clean or replace quickly. Avoid filters that take too much time.
- Cartridge filters are easy to swap but can be costly
- Canister filters have larger capacity and easy cleaning
- Internal filters are simple but smaller in size
- Sponge filters are cheap and easy to clean
Noise And Energy Efficiency
Quiet filters create a peaceful tank environment. Loud noise can stress fish and disturb people.
Choose energy-efficient filters to save electricity and reduce heat in the tank.
- Look for filters with low noise ratings
- Check power consumption before buying
- Use filters with energy-saving motors
- Place filters on soft surfaces to reduce noise
Installation And Maintenance Tips
Choosing the best filtration system for your species tank is just the start. Proper installation and regular upkeep keep your tank healthy. This guide gives simple tips for setup and care.
