Wow, I forgot to check back to this thread. I've actually gone a different route. I'm going to change to a herbie overflow setup. And for this to be silent the drains have to be fully submerged in the sump. So I've changed to a standard filter sock system, bioballs for wet/dry, scrubbies submerged, and an acrylic rack for growing pothos. I will post pics as I build it. Stay tuned. P.s. My wife is 8.5 months pregnant with our first child so it might be a slow process. Thank you for the diagram, shame I couldn't use it
