As for GFCI it will still trip if the power bar dosnt so it as nother levle of safty. I would try and sped out the power a little bit if you can you will have to check the plugs are not on the same curcit in the hole room though. if there are you can you one or two plugs ( two is better then one). a surge protector will also help protect your light and pump ( they are not cheap
) I hope this can help you out little.
this is just my $0.02 I am by no means an eletrical expert of any kind.
