The Fluval Fresh F90 features a 3-stage filtration system that ensures optimal water quality for your aquarium. The first stage is mechanical filtration, where a foam pad traps debris and particles from the water. The second stage is chemical filtration, using activated carbon to remove impurities, odors, and discoloration. The final stage is biological filtration, where beneficial bacteria colonize on the biomax media to break down harmful ammonia and nitrite into less harmful nitrates. This comprehensive filtration system helps maintain a healthy and balanced aquatic environment for your fish and plants. **
