I've heard that I should have mechanical filtration before biological so the bio media won't clog up as easily.What I've done in my Quietflow 30 is to have a media bag of matrix to the left of #1 (i.e. put #4 in a bag and put it in the water intake area).
How thick is the mesh bag (#3)?
I wonder if #1 is causing the flow to be hindered a little bit, resulting in water going over the bypass.
