Alright, got the tank filled and have my rock in and it's cycling. The room it's in can get 0 light unless I open the blinds and take down the plywood I have covering the window. Should I leave the lights off the whole time. I want to eliminate any cyano before it even starts and want to know what to do to make that happen. Also when I move my fish, shrimp, and snails, should I qt the snails in total darkness in case some cyano latched on to their shells? Btw, the tangs are doing great, the blue one had ich. It showed up the next day so I have them hypo'd right now and they(like the firefish and wrasse) seem more active than they were in normal salinity. Is there something weird going on or is that normal? I'll get some pictures up when I get a new camera, mine had a fight with concrete and lost.
