It's only a cheap walmart 10 gal tank that I siliconed acrylic baffles in it. I went to home depot and they even cut out the sized pieces for me so all I had to do was glue them in place. As far as microbubbles, I don't know yet, my intake back into my tank is very leaky and I'm probably going to have to redo it. I'll update when I get that done.
