I just about have a new tank togeather for the move I'm making except for the light. I need to choose between a 40 watt 10000k and 460 nanometer actinic or an 80 watt 10000k 6700k and dual actinic 460nm and 420 nm of which I have no idea of what I just said. Any and all suggustions will be greatly appreciated. This light will be on a ten gallon plain black tank.
