Filtration plays a vital role in any aquatic or semi-aquatic habitat. Water filters clean the water via three main processes: mechanical, biological, and chemical filtration. Mechanical filtration physically removes particulate and debris from the water, while biological filtration utilizes beneficiall strains of bacteria that help break down organic waste. Chemical filtration, such as carbon pads, chemically binds with impurities and organic wastes, thus removing them from the system. Regardless of how much filtration is present, it is important to maintain a high level of water quality with frequent water changes. Filters also provide aeration and water circulation, lending to a healthier, and cleaner, environment for your pet reptiles and amphibians.
