Your fish tank water was cloudy yesterday but today its clear how?

Biological Filtration: Beneficial bacteria in your filter or substrate have broken down organic waste, clearing the water.

Mechanical Filtration: Filter media, such as floss or sponges, have trapped particles causing the cloudiness.

Chemical Filtration: Activated carbon or other chemical media have absorbed impurities.

Aeration: Increased water oxygenation can aid in clearing cloudy water.

Reduced Waste: Fewer decaying plants or overfeeding might have contributed to the previous cloudiness.

Waiting: Sometimes, cloudy water resolves itself if given time.
