That is really wierd... If the breaker is going after 5 hours there has to be a cause. You tried a differnt power bar, its not that.
What all is pluged into the power bar that is tripping. Try to find what is kicking in at the 5 hour mark buy removing the non-esential plugs one at a time. Ie, skimmer, then light 1, then 2 ect... you can keep the equipment running by using an extension cord. This should let you isolate the current leak.
