Aquarium filtration types

Filtration is fundamental to aquarium environment. There're 3 basic types of filtration: mechanical, chemical and biological, only when they're all available can a truly healthy and balanced environment be maintained for the fish.


Among the 3 types of filtration, biological filtration is the most essential of all. It's an effective approach to the removal of ammonia, nitrite and nitrate from water by biological conversion of a toxic solute to a less toxic or harmless solute.
