Piping configuration

Well, there's the problem wherein the one side where the E-drains are won't get proper flow through.

Have my main in one overflow, emergency in another and works okay.

Running a trickle through the emergency but was also worried about going stagnate so drilled a 1/4" hole high on the standpipe, threaded in a elbow with a line going to bottom. Not sure if may a differance but my tile fish went AWOL for a month and just got fatter in the e-overflow.
