Nice!Not bad, each tank has two 3/4" drains with Herbie overflows into a acrylic overflow box. they then combine into a 2" drain pipe underneath. Most of the noise is coming from where the water enters the sump/filter sock area. I extended to pipe to submerge the 2" drain, 1" into the sock and that cut about 70% of it. Over flows are quiet. once everything is cased in and cabinets hopefully be almost nothing. fingers crossed.
...are you planning to leave it open top, or cabinet/enclose the lights also?
