That's fine and while I agree that a GFCI may not have helped in this case I'm glad to have all my tank equipment protected by GFCI receptacles. Fire hazard or not, at least I've taken the precaution to protect my safety and that of my family as far as shocks go. Nothing is foolproof, but if code requires GFCIs in any wet location, bathroom for example, why would I not take the same precaution with my aquarium?

Some GFCIs are designed not to reset automatically in the event of a power outage or circuit breaker trip. If I'm not mistaken these are generally the plug in adapter versions designed for use in a shop with power tools - you don't necessarily want your circular saw or belt sander starting up on their own after you go reset a tripped circuit breaker.

I'm fairly certain that most receptacle type GFCIs do not need a manual reset if there is a power failure or circuit breaker trip. Unless they are tripped by an actual ground fault, they should power up again automatically when power is restored to the circuit. I've just tripped and reset the circuit breaker on two of my GFCI receptacles and both of them worked without having to reset the GFCI itself. There are a lot of products out there these days and to speculate or opinionate about GFCIs is not in the best interest of safety.

With respect to a house not being grounded, if you research the subject, adding a GFCI is actually one of the recommended solutions for making a non grounded circuit safer. Since the GFCI senses current differential between the hot and neutral, a ground wire is actually not needed to make it trip. If you are the path from hot to ground/earth, the GFCI will save your bacon even though there is no ground wire in the circuit. Although your house wiring may not have a ground, earth is still there and there is the potential for you to become the path to it.
