shutup

Since you haven't added water now's your chance to consider a Herbie. Just needs one extra drain compared to Durso, Stockman etc. and since Herbie doesn't draw air, no gurgling or splashing in the sump.

I've heard or rather didn't two high flow setups (one 1900gph other 2000g) and loudest thing was the return pump, nothing from the plumbing. Where you might get some noise is the drop from the overflow lip into the chamber but can adjust standpipe to get that though.
