I just changed my 100 micron filter sock to a new one and my protein skimmer just suddenly shot out tons of micro bubbles out of the exhaust. It seems like my pump is putting in more water than air, so I checked my air line but its fine. I have no idea whats happening and would like an answer. My system is a brand new 90 gallon with a 40 gallon sump, done cycling a month ago with one fish in the system currently.
