I have recently gotten a 65 gallon tank and I want to upgrade the lights so that I can have corals. The tank is 3' deep. I currently have two 36" T5 Lights and 2 24" power compact 50/50 bulbs on the tank. I want to upgrade to LED, but not sure how. I want to have soft/leather corals, so I shouldn't need a lot of light, but I am not sure about the spectrum. I have tried to read up on it, but I am having difficulty understanding what setup I will need.
