The Paradise current switch isn't anything to worry about unless it's going out, it's common. Some nights it goes south, some nights north, some nights it can't decide...
I've seen Tiki bar go from virtually no current to screaming current in less than 5 minutes, another place visiblity from 100'+ to 25' max and who knows what the heck that was....
I've seen what looks like fish feeding on the surface, you see it and can hear it - it moves around. You see flat areas surrounded by chop - that's all current doing something.
