Mechanical Filtration: The filter removes solid debris such as fish waste, uneaten food, and other particles from the water.
Chemical Filtration: The filter uses chemical media such as activated carbon to remove dissolved toxins, impurities, and discoloration from the water.
Biological Filtration: The filter promotes the growth of beneficial bacteria that break down harmful toxins such as ammonia and nitrite, thus maintaining a healthy balance in the tank.
