How do you get the chamber 1 to do the surface skimming and act as an overflow?
When I look inside chamber 1, I see that the water level is equal to other chambers and I don't see any waterfall effect so there is no surface skimming.
Do I have to completely plug up the grate openings in the bottom and middle parts of chamber 1?
