![]() I am using a plug, but that would work for adjustment as well. Will try that. Thanks. So if I get the setting up top right, will that cure the bubbles down in the sump? These are not microbubbles, but rather huge boiling effect.

![]() With a filter sock on the output you'll be fine for bubbles, I was running without them, so the bubbles freely travelled to the return. After lots of fine tuning the duroso was quite, the bubbles on the output where louder than the intake of water at the top. I swapped to a single herbie instead of my 2 duroso's, if you have that ability I'd recommend it.
Also, if the main input to the duroso is getting air you will have a loud bubbleing, i used a 90 and brought the intake down 4" under the water line, it was well needed, stopped large bubbles, only had smaller ones from the air intake.

![]() Thanks for everyone's help. Last night I made a "zig-zag" with 4 - 45° elbows and that reduced the boiling by about 75%. Still going to try a few tweaks to this and try to get it even better. Maybe play with the last downtube length and depth in the water.
Cheers, Leon |

![]() started with Dursos, switched to Herbie due noise in the lines and gurgling in sump. No air, noise.
As for hole size with Dursos, I had 2 drains and flowing ~2000gph, in each cap, hole was only a little bigger than 1/8"
