Canisters? But what's the fun in that? j/k
I just watch the durso video. In my experience if your primary drain for the Herbie is sufficiently below the waterline to create continuous siphon, it is as silent as ay properly implemented durso standpipe. I think where the noise is introduced is when you have the trickle stand-by (i.e. second drain). As the return fluctuates, it increases the waterflow to a point sometimes a bit more than just a trickle - this results in increased air into the standpipe. I occasionally hear this at night when fans aren't running and other background noise. But overall, it's just as noise free as the durso approach in this video. Just sharing as there are options to have a quiet overflow.
This is a picture of my Herbie awhile back. I've since cut the primary drain (with strainer) by a couple inches to eliminate the swishing sound. I then also cut my second trickle drain a bit as well. I left the third as is.
