Maintenance Tips
Regular cleaning keeps mechanical filters effective. Dirty filters reduce water flow and allow waste to build up, which can increase harmful bacteria.
| Task | Frequency | Notes |
| Rinse sponge or filter media | Every 2 weeks | Use tank water to avoid killing good bacteria |
| Replace cartridge | Monthly or as needed | Do not replace all at once to keep beneficial bacteria |
| Check for blockages | Weekly | Clear debris to maintain water flow |
| Inspect filter parts | Monthly | Replace worn parts to keep filter working well |
Biological Filtration Techniques
Biological filtration helps keep aquarium water clean and safe. It uses bacteria to break down harmful waste.
This process transforms toxic substances into less harmful ones. Good bacteria play a key role in this system.
Bacteria Colonization
Bacteria colonize on surfaces inside the filter. They form a slimy layer called biofilm.
These bacteria convert ammonia into nitrites and then nitrates. This process is called nitrification.
- Ammonia comes from fish waste and leftover food
- Nitrites are toxic but short-lived
- Nitrates are less harmful and removed by water changes
Media Selection
Filter media provides a surface for bacteria to grow on. The right media improves filtration efficiency.
Common media types include sponges, ceramic rings, and bio balls. Each has a large surface area for bacteria.
- Sponges trap debris and host bacteria
- Ceramic rings offer many tiny pores for colonization
- Bio balls allow water to flow through easily
