Bobby, if anything your water level in the sump looks low... but I don't think that is the problem. I'd try a couple things.
Remove the wedge pipe - is the water/foam level still high?
if yes then it's the pump.
if no then the wedge pipe is seating incorrectly or there is an obstruction.
Remove the airline from the small gray elbow fitting on the riser pipe.
if the level goes down you have a restriction in the fitting.
if no change, move on to the pump.
Pull the air venturi fittling off the front of the pump. Remove the airline and look to see there is nothing blocking the inlet. Any debris will restrict the air and allow the pump to push too much water into the skimmer.
Pull the pump out and remove the volute (front cover). Make sure you don't lose the black plastic washer that goes between the impeller and rubber bushing. See anything stuck in the needle wheel? Now pull out the impeller - you may need some needlenose pliers to pull it out. Is the ceramic shaft cracked? Look to make sure there is another black washer at the bottom of the shaft, though sometimes it sticks to the bottom of the impeller. Reassemble and try it all again.
I have the IN-250 and the only thing that makes it overflow is if I restrict the airline or have the wedge pipe more than 2/3 closed when I restart.
One more thing to check. This happened on an older Octopus skimmer I had with a similar wedge pipe. Make sure the "Open" marker is actually where the wedge is open. That old skimmer had that Open mark on the closed side so instead of open the wedge was blocking/closing the flow.
I'm probably over-explaining this but hopefully one of these things will narrow down the problem.
