First night I used the needlewheel then yesterday I tried to used the meshwheel. Both didn't show microbubbles. At first I thought there were bubbles coming out of the exit pipe, but found out that the bubbles actually were coming from my main tank drain pipes.

The skimmate was brown and wet, so last night I opened the exhaust pipe gate to make the skimmate darker. I'll take some pictures tonight when I get home.
