Ideally the baffles should be about 1/4" to 1/2" apart from each other in regards to the bubble trap. The piece of glass/acryclic that runs from the top of the sump to near the bottom of the tank should be about 1" from the bottom of the sump. Here's a good DIY video on making a sump.

, they would survive back to the tank rather than being destroyed by the skimmer.
