Filtration

With so many different saltwater aquarium filters to choose from, it can be really hard to choose the right one. And, if you are a beginner in the saltwater hobby it could be impossible. Saltwater fish and marine animals have completely different needs than freshwater fish when it comes to water quality. They are much more sensitive to water conditions and poor water quality can quickly lead to disaster. Understanding what each type of filter does can help you choose a saltwater filter that meets your needs.

Although the main function of an aquarium filter is to clean the water, filters also offer some other essential benefits. A filter keeps the water in the aquarium circulating. In their natural habitat, fish and marine life live among the swelling tides of the oceans currents. The filter helps keep the water in your tank from becoming stagnant. And, it also keeps a constant supply of air circulating through the water.
