I never run my Hebrie with a trickle down the drain.

Filter socks , water levels in the return pump are the usual causes of fluctuations.

Filter socks are good as long as there kept clean otherwise I think there a PITA. I run an ATO using the double float system into the return pump area, which gives me constant level accuracy for the pump.
I use filter floss in my bubble trap area just before the return pump chamber for cleaning and don't use socks anymore, and always trickle down the emergency overflow, It works well for me. I just maintain a clean Herbie strainer in the overflow box.

too much noise for me , a trickle down my emergency would drive me nuts....and i dont submerge my emergency as i like to know when its going off so i can fix it , if its submerged you may not know if the main is clogged unless its creating bubbles

My water level is the same level as the top of my emergency pipe so I only get a few drops down the pipe, can't even hear it at all until it starts running out faster, then I clean the herbie strainer and it's fine again.
