How Does an Internal Filter Optimize Water Quality in a 50 Litre Aquarium?

An internal filter optimizes water quality in a 50-litre aquarium through three main processes: mechanical filtration, biological filtration, and chemical filtration.

Mechanical filtration involves trapping solid particles from the water. The filter draws water into its system, where a sponge or filter pad captures debris, waste, and uneaten food. This process removes visible impurities and helps clarify the water.

Biological filtration relies on beneficial bacteria that grow on the filter media. These bacteria convert harmful ammonia and nitrites, produced from fish waste and decaying matter, into less harmful nitrates. This process is essential for maintaining a balanced and healthy aquatic environment.

Chemical filtration uses materials like activated carbon to remove impurities and toxins. The filter passes water through the carbon, which absorbs pollutants and improves overall water clarity and smell.

Together, these filtration processes cycle and purify the water, creating a healthier habitat for fish and other aquatic life. An internal filter, therefore, maintains optimal water quality by continuously circulating and cleaning the water in the aquarium.
