Micro bubbles

[GMGQ]

Yeah, my sump is like Marc's F-design, with the corner bubble tower. I still got crazy bubbles in my display tank.

I choked back the return pump quite a bit, but i still get noticeable bubbles.

I've been experimenting with this leftover piece of acrylic I have, that's sorta like a C-shape. I put it around the intake of my return pump, to sort of shield it from the bubbles falling into the middle section of the sump. It sort of helps.
