Thanks for the input guys.
SVTour thanks for the pics, Once you see it it makes it easier to understand.
redox I don't have the schuran up and running right now, I moved and bought a bigger tank. I hadn't figured it out, or maybe I had. I was just going through a hell of alot of bubbles and it wasn't helping my Alk. But it was a very heavily stocked 180 sps. I did buy 2 peri pumps though, so I hope when I set it up on this tank it will make a difference
