In the past, aquarium lighting was an often-overlooked aspect of aquarium keeping. However, we now know that proper lighting plays a vital role in the success of all aquarium systems.

Why is Lighting Important for Aquariums?
In its most basic role, aquarium lighting allows hobbyists to observe aquarium inhabitants. But more importantly, proper aquarium lighting provides vital energy to photosynthetic plants and animals. As the primary light source (and in most cases, the only light source), proper aquarium lighting is essential for any system that contains photosynthetic organisms such as plants, anemones, or corals. Lighting also influences fish behavior and physiology and is vital for the overall health and well-being of the entire aquarium.

Aquarium lighting is the most significant yet overlooked component of any aquarium, as many people are not aware that proper light intensity is required for invertebrates and corals to survive. It is a fact that plants, corals, and invertebrates are in definite need of light for photosynthesis to generate food and energy. Thus, if the light condition is not proper then invertebrates and corals are not able to receive the sufficient light from the aquarium lights and then it becomes difficult for the aquatic plants and corals to survive. Therefore selecting the right aquarium and fish tank light is essential to prolong the life of coral, fish, and aquatic plants.

Water quality (in which I include water movement) is top of the list in importance when it comes to keeping a saltwater aquarium. Closely following water quality is aquarium lighting, as much life on the reef depends on it.
