I just upgraded my BC 33 from stock led to Steve's LED with iridescent booster and Hurricanex controller. I've read through everything I can find and still can't figure out what all the channels (besides 1-4) are for. I set it up according to the example given in the manual, but I don't want to hurt my corals or anything by having channels 5-16 set at something wrong. Can someone please help me understand how that works?
