What kind of problem? I run herbie on my tank and I always do water change from the sump by turning off the return and turning it back on after the change and it takes around a minute or so for the overflow to get back to its old settings. The trick that I found to work for me is to have a small trickle down the emergency drain; otherwise, you might have to adjust the herbie's level from time to time which is a bit annoying.
