Do you need a filter for freshwater aquariums?

Yes, a filter is essential for maintaining clean, oxygen-rich water in a freshwater tank. It removes waste and supports healthy water parameters for your fish.

What media do I need for freshwater tanks?

Most tanks benefit from a combination of mechanical, chemical, and biological media. This layered approach keeps water clear and safe by addressing different types of waste.
