I got the wire initially with my icecap ballasts(no longer use) the new stuff I got from an electrician. You should be able to get it from an electrical store
you can try manual removal, or if your tank is big enough and you can keep one you can try a sailfin tang. I have heard sailfins eat it but its not a definate answer as some might eat it and some might not
I lived in the states for a few years and was into tropicalfish which lead to salt, I lived on the road at the time always travelling so couldnt get a tank till I moved home to NZ. Dave at HFF was very very helpful in my early years of keeping a tank, reef has been helpful as have a number of reefers who I have met over the years
By basic I'm meaning something like ours, not something like witherspoons totm last month, his backroom looks more like a laboratory than a fish tank room
I seriously doubt that its the lights that make any system that nice, much much more to it than that. His tank would probably look amazing with t8's. It is a very basic setup also
