How Does Filtration Work in an Aquarium?
Filtration in an aquarium works by removing debris and harmful substances from the water. The main components of filtration are mechanical, biological, and chemical processes.
Mechanical filtration captures solid particles. Water passes through a filter medium, like foam or sponge, which traps dirt and debris. This process keeps the water clear and clean.
Biological filtration involves beneficial bacteria. These bacteria live in the filter and on surfaces in the tank. They convert harmful ammonia and nitrites, produced from fish waste and uneaten food, into less toxic nitrates. This step is crucial for maintaining a healthy environment for fish.
Chemical filtration uses materials like activated carbon. This component removes impurities and odors from the water. It works by chemically adsorbing harmful substances.
The filtration process operates in a loop. Water flows from the tank through the filter and returns clean to the aquarium. Maintaining this cycle ensures a healthy habitat for aquatic life.
In summary, filtration works effectively by combining mechanical, biological, and chemical methods. This process keeps the aquarium clean, safe, and pleasant for fish and aquatic organisms.
