I'm a Herbie club member

[Delphinus]

I've been kind of wondering if something like that could work for dual overflows because I have the same situation with my cube tank, dual overflows with Dursos. It's silent enough but I like Herbie better and the tank has had chronic microbubbles since day 1 due to the flow through sump. I was thinking about something like this for when I go to move the tank.

So .. um .. thanks for the proof of concept.
