Getting a synergy overflow quiet?

[lbacha]

Are you running the synergy overflow? I have my pumps down to probably about 1500g right now.

We have steps in the right direction!!! So much better! I pulled one half of the two 90’s ,on the secondary, off to raise the level. This helped. Then I had the idea to silence the waterfall. The majority of noise is from the overflowing water through the weir. I went to scrounge through my fish box of random stuff to see what I could come up with. I found a sheet of cross stitch fabric that I had used to DIY an algae scrubber in my AIO. Perfect length and width. Disclaimer, do not remove the weir of the synergy while the pumps are running. I did have some overflow onto the floor before I could shut the pumps down.
Anyway, I cut sections of the cross stitch mesh and rolled them up and placed in each of the 4 sections of the inside front overflow box. Whatya know! Not silence, but vastly better than before. I can actually hear the surface breaking from my returns!
Still some dialing in but we are getting there! This overflow design is stupid!! But my wife is much happier!!
