A fellow coworker of mine showed me this website today. His brother works at this company that manufactures custom LED lighting. This website allows you to modify light spectrums for both saltwater and freshwater tanks, and is available for all tank sizes. You also have the option of buying lighting patterns they have available, but thought this was particularly cool depending on what type of effect you are looking to get from your aquarium. Check it out!
