Tank crash caused by Wal Mart fan!

[frd72]

just wondering, is this cause by electric current? short circuit on the water?
causing all of your fish to be sick? even if you don't have it GFCI, your circuit breaker should go off. Just my thought. maybe you should consider checking it??
It happen to me once but not a fan, a battery operated led touch lamp, i think with four AA battery all fell on the sump overnight and leave no problem with the main tank, the skimmer did all the clean up. I empty the skimmer cup and saw all the juice from the battery..

thanks,
