As you can see i have a VERY VERY big problem with microbubbles, they start right where my overflow tube dumps to the sump (mostly because of the bubbles in the overflow line, as shown in pic below). Then if you take a REALLY close look at the display tank, the water looks slightly cloudy, this is because my return puts out these microbubbles. I can see them coming right from the Tom aquatics nozzle. I know its not the nozzle because it did the same thing with a homemade return.
