Diablo xs200 stopped producing micro bubbles

[Savant]

I have had this Diablo skimmer for about a 1 1/2 years and it has worked awesome. This weekend I upgraded my plumbing system to all flexspa piping. When I fired up the return pump, verified no leaks, I brought the skimmer back on line. The first thing I noticed was that the skimmer chamber filled with water but the bubbles in the chamber were comparatively very large in relation to the tiny micro-bubbles usually produced. Where the chamber usually had a milky white color it now had a grey color due to the larger size of the bubbles.

Having worked as a chef for many years I know that things like oils can prevent foams from forming in media such as egg whites and soda pop. Im kicking myself now for not flushing the spaflex before installing it but that opportunity has passed. Perhaps there was some type of oil/ contaminate in the pipe?

So, has anybody experienced this situation with their skimmer not producing micro-bubbles and did it resolve itself? The diablo has a sicce1000 pump, I verified that all of the needles on the impeller are still intact and the pump does not appear to be clogged and will move a very large volume of water if I open the gate valve fully. I have tried stopping and restarting the pump several times with no success.

Could be something in the water from the plumbing work. Give it a couple of days with the skimmer running.

Im noticing a very thin film of something on the surface of my sump. Any suggestions on how to soak it up/remove it? My sump is a 100 Gal stock tank so it has some size to it. If it was small I would try laying paper towels across the top but thats just not feasible. Is there an absorbent product somebody know about? My corals and fish seem unaffected but I dont know how long that will last if I am unable to skim.
