That issue isn't skimmer specific, I've had the same issue with both a downdraft and a regular needlewheel. What I did last time was turn off my auto-topoff and just run the skimmer as low as I could. I basically did about a 10g water change with the skimmer, topping the tank off with fresh made salt water as the skimmer sucked out water. It slowly settled down and the foam cannon effect went away. It was easy as the skimmer I was using had a drain. Aside from that, numerous water changes and carbon are the only rememdies I've heard of.
