Thanks for that. That picture was just an example. I'm looking at similar design sumps from Trigger, Synergy, others but with a similar filter sock section. I do plan on a BeanAnimal overflow, water will enter the sump below the waterline.I’ve got the waterbox Infinia sump and if you run the baffle for the refugium and low flow (3-5x turnover) it works great without socks.
In the sump you posted example of it would all depend on flow rate, looks like there’s a drop from the intake to the next chamber. Also look into modern drain setups utilizing gate valves for siphon overflow with emergency backup drains (herbie, bean animal, almost all modern systems utilize a version of these). Then make sure the drain is underwater in the sump and it greatly limits splashing and bubbles. So nice. These factors help a great deal with quieting things down.
