Elevated Fuge with return to tank - bubbles, any help?

[ciphros]

After nearly 6 months, we finally have our new 269 gallon in-wall tank up and going. I went with an elevated refugium for this system with the hopes of feeding pods to the tank without them having to go through the pump like in our old 155. I have the Fuge mounted overhead, and the tube feeding into the tank is near the back wall (eurobraced top, so it's out a bit). I get a ton of bubbles from the line into the tank, looking for ideas that will allow me to get rid of this issue. Any help appreciated.

Here's the Fuge:

Here's the plumbing leading to the entry to the tank (sorry, older photo, will try to get a newer one up with stuff in the tank):

bump...anyone? Any ideas at all? Short of creating some sort of an acrylic run-out tray, I haven't come up with any ideas. Someone else has to have put their fuge above the tank and have it feed into the tank right?
