Fluctuations in the return chamber create fluctuations in how the pump operates , this then leads to fluctuations in the overflow , the gatevalve is set based on the pumps running condition so any fluctuations on how it operates is derectly linked to your herbie oveflow , It is very common in herbie set ups

Throttling back the pump won't do anything as its not the speed of the pump but the consistency it's running at.

Say what u want but i've had numerous tanks with herbies, no ato and no problem keeping them quiet. A valve will make all the difference because the fluctuation in the return compartment is now irrelevant because of the back pressure caused by the valve. A valve does nothing to change the speed of the pump. I'm not sure where u got that from... It just gives it a consistent restriction to pump against... Anyways... I'm not here for a debate. I'm just offering suggestions for duncan.

Yeah your right , since it works for you it must work universally for everyone as is the law of reef and you've def got more experience then me from what I can tell , if that's what we're gong by lol pay no attention that several people have pointed it out as well but when your right your right , right?;p

Would be simple enough to test .......fill return chamber , set herbie , let chamber drain , see if herbie stays set....easy peasy
