How is the water in a fish tank filtered?
An aquarium produces waste materials for a number of reasons. One reason is the biological reactions that take place in the water; these could simply take form of uneaten food that was left to spoil, or by waste materials of the fish themselves. But whatever these waste sources are, there are usually three general ways to remove and clean off these waste materials out of your fish tank. When we speak of the natural processes involved in filtering the water inside a fish tank, we talk about biological filtration. Beneficial bacteria is the most common and effective agent of this filtering process, being able to break down dangerous toxic materials into less toxic substances. Synthetic materials that are used to combine with waste materials are the work of a chemical filtration process. These waste materials react with the synthetic material, dissolving it and transforming it into a form that can be collected and thrown afterwards. One good material used for chemical filtration is activa
