A good filter is an indispensable piece of equipment for any professional or amateur aquarium. Simply put, a good filter makes sure that your fish stays alive. While the importance of a pump is obvious, because it moves and oxygenates the water so that your fish don't die for lack of oxygen, the filter is also crucial for the health and well being of your aquarium as a whole.
Not only does it mechanically separate debris from the water, making your water clear and making sure the fish aren't irritated; it also makes sure that your water is safe. The biggest threats to an aquarium system are things that you cannot see. These are the chemicals that build up in the water.
Since you're fish eat and go to the bathroom in the same place, namely your water, it is very important that the water stays clean. It must clean enough for your fish to live and eat in. When fish go to the bathroom in the water, chemicals like ammonia build up. These pose a direct health risk to your pet if left untreated. The filter's job is to make sure that the water is safe from chemical threats like ammonia, nitrates and nitrites.Aquarium filter
comes in different designs; one particularly great design is the Whisper EX 20. This design works by using a pouch system. The filter pumps the water into a pouch and the pouch has chemical ingredients that filter and attract chemicals that build up in the water like ammonia, nitrates and nitrites.
