Skimmer not working after large water change??

[BLANKENSHIP76]

I did a 20% water change and then the next day did like a 40% water change in my 120 w/30 gallon sump. Ever since the 2nd water change my skimmer has not been producing any foam.

Is this normal???? It has been like 3 days now.

Not sure, but I think you just got rid of a bunch of your skimmate when you did your water change. You might have to wait for your critters to produce some mor waste products. And that's not a bad thing IMHO.
