Mechanical Filtration
Mechanical filtration removes large particles from the water. This includes debris like uneaten food, fish waste, and plant matter. An efficient mechanical filter often contains sponges or filter pads that trap these particles. Regular cleaning or replacement of these components ensures effective filtration.
Biological Filtration
Biological filtration utilizes beneficial bacteria to break down harmful substances. These bacteria convert ammonia, produced by fish waste and decaying organic matter, into less toxic nitrites and then into nitrates. Establishing a proper biofilter is essential for a balanced ecosystem. Use filter media that supports the growth of these bacteria.
Chemical Filtration
Chemical filtration involves the use of media that adsorbs or removes specific substances from water. Activated carbon is a common choice. It helps eliminate impurities, odors, and discoloration. Other chemical media may include phosphate removers and zeolites. Choose an appropriate media based on your aquarium’s specific needs.
- Select the Right Filter: Match the filter’s capacity to your tank size. A filter rated for a larger tank provides better water turnover.
- Maintain Regular Cleaning: Clean filter media regularly but avoid over-cleaning beneficial bacteria. Stick to a maintenance schedule.
- Monitor Water Parameters: Regularly test your water for ammonia, nitrites, and nitrates. This helps you gauge the effectiveness of your filtration system.
- Use Carbon Judiciously: If you opt for carbon, replace it every 4-6 weeks to maintain its effectiveness without leaching impurities back into the water.
Understanding these filtration types and their functions ensures you create a thriving aquatic environment.
