Fish tanks can be a great addition to any home, but in order for them to thrive, it is important to know if they need a LIF (Lighting Filtration) system or not. While some fish tanks may not require one, many larger and more complex aquariums will benefit from the use of this type of filtration system. A LIF system typically consists of three parts: lights, filter media and pumps/power heads. The lights produce light that helps promote photosynthesis in aquatic plants and corals while also providing illumination for viewing purposes. Filter media captures debris and waste materials before they can foul up the environment within the tank while pumps circulate clean water throughout the aquarium’s ecosystem. By having these components working together as part of an overall aquatic environment management plan, aquarists are able to create safe and healthy habitats for their fish without sacrificing aesthetics or quality of life due to poor water quality conditions. In conclusion, it is highly recommended that larger fish tanks should have a LIF system installed as part of their setup in order to keep their inhabitants healthy and happy!
