This is the second one of these I have and I'm done with them. This one

is doing the same thing that my first one did. It blew the circuit on
the gfci outlet. I reset it and it runs for a few min and the circuit
blows again. Its not the outlet because anythig else plugged in still
stays running.


Anyways at my office we have a 300 gallong salt water aquarium and this

is the kind of pump we use there and it runs 24/7 and its been ruinning

for over 2 years straight with no break downs. The only difference will

be that if I get one mine will have to live outside. I will probably
make some kind of cover for it.=20


Thanks,=20
