Herbie overflows and gravity fed skimmer?

[Delphinus]

Is is possible to combine a Herbie overflow into a gravity fed recirculation skimmer?

i dont see why not, you are just tuning the overflow by doing the herbie. there is still the same amount of pressure, so providing you have enough head pressure, ie drop from your display to your sump or skimmer, it should work. IMO i should add.

I also agree there is no problem with doing that. In fact, I have a long term plan to do exactly the same thing. I'm guessing that you will have it done before me though.

I wouldn't be so sure I've got a long way to go.

I'm just curious because it seems to me that you could put the valve between the overflow and the skimmer, and that would adjust the water level in the overflow, but then you might need a second valve downstream of the skimmer to adjust the water level in there. If that valve is set to a position "more closed" than the upstream valve then it becomes the master valve controlling both overflow and skimmer water levels. I guess if the skimmer was set low enough then this wouldn't be a problem .. ?? I'm just trying to wrap my head around what would happen. Would one valve downstream of the skimmer suffice do you think?

This may work. Just an idea.

or maybe you could move the valve on the other side of the tee
