While performing a water change the main return pump should be off and the skimmer off too as well. After performing the water change when the main return pump goes back on, you should to wait 5 to 10 minutes for the water level in the skimmer chamber of your sump gets stable. Then turn you skimmer back on.
If the sump design is right, the skimmer chamber should keep the same water level at all times while the skimmer is running. There is no need to be readjusted. I only adjust mine if I want to get wet skimmate for while, then after a few days I'll adjust it back to what it was.
That is exactly what I do, except I usually wait 30m after the system is running again before turning the skimmer on. The skimmer chamber is constant level.
I think the water level might just be too high for the skimmer. It's ~8 inches from the bottom of the sump and my sump doesn't have an adjustable water level.
I did end up getting a Bubble King 150 for a steal. I haven't broken it in yet, but the recommended max water level is ~7.5", so I'm on the lookout for a skimmer stand to lift it up a few inches.
