I have a 57g tank, that is 36" wide and 20" tall. I'm planning on soft corals and some LPS, no SPS. I'm settled on this light, but I am completely lost when it comes to optics and LED colors. I'm assuming I can just go with the standard color scheme. But can you recommend what I should be selecting for the optics options (60, 90, 120) for this kind of set-up? And if there are alternative color options that are pretty common, maybe what those are, pros/cons? One last question, if using an apex controller, should I select the value light? It doesn't same on the website if this is VDM compatible, just says dimmable. And if I need to go with the controllable fixture, is this compatible to use with the apex. Thanks for the help.
