Hmm.. one extra hot shower and pop.. the whole house goes out.

GFCI's sometimes trip for reasons unrelated to people being
electrocuted. Thunderstorms are purported to cause them to trip. I've even
experienced random trippings without the help of thunderstorms.
Because of this, you probably don't want some critical circuits on the
GFCI.. like your refrigerator and furnace. By this same reasoning, it's
worthwhile considering running an airpump in each tank plugged into a separate,
non-GFCI protected, outlet so at least there's still water movement if the
And to tie this back into plants and aquarium keeping, my GFCI recently
saved one of my fish tanks and possible the entire house when the (grounded)
light system failed (still don't know how or why) just after I left for work
one day recently.
