I'm thinking about purchasing a led light fixture off eBay or amazon. I want to get one that can be used to raise corals and anemones. I don't want to spend too much money on the lights so my budget is around $60 - $70. I want one that makes the daylight look blue and the night to look dark blue. Anyone have any suggestions or know a led light fixture that may fall in between my budget. Also, my tank is 4ft long so either a strong one that's smaller in length or one about 4ft long. Thanks!
