bckane, I just saw, and replied to, your PM. Figured I'd post the answer here, also:

As far as the spacing of my baffles, my kids have lost my last and as of now only tape measure, so I'm guessing here. The first compartment, were the main tank drains into and the skimmer is, is about 8.5 inches long. The size of this compartment was dictated by my skimmer, a Coralife SuperSkimmer 65, so it had to be that big. The bubble baffles are 1 inch apart. I would have like them to be 1.5 to 2 inches apart, but space was at a premium in this tank, so I set them at 1 inch. Made siliconing them in place a challange. I did the center one first, that was easy. With the outside two I layed a thick bead of silicone down first, and slid the baffles in place, moving them towards the center baffle. This way there was some silicone on the inside of the baffle, since I wouldn't be able to get my fingers down inside to put more silicone. This did end up leaving what looked like large gaps, but the silicone I place on the outside of the baffles is holding just fine. The middle compartment is the return compartment where my pump sits, it's about 7 inches long, and the fuge is about 6 inches long. Now that it's been running for a week, I think if I were to do it again I wouldn't have incorporated a fuge in this sump, and would have left the remaining 13 inches in the tank as a larger return area, and increased the bubble baffles to 1.5 inches. That's becuase of the evaporation. With that small return area, I've got to top off pretty much every day. If I were to install an auto-top off that issue would go away, so 'in the future' I'll look at doing that. Hope this helps.
