One additional comment about GFCI.
GFCI can sometimes trip for no obvious reason, and even if all your equipment is good. Some items, electronic MH ballasts come to mind, can trip a GFCI even if they are good.
Since you loose power if the GFCI trips, and you must reset it, it can be a disaster if your away for a few days and it trips then. A couple of times I had my GFCI trip when I was away, and lost almost everything in the tank. It was a SW reef tank too, and those are almost as expensive as a FW planted tank (grin).
I would say that if your going to be away for an extended period, plug the critical equipment, such as the filtration system, into a Non-GFI outlet.
