There's a big silicone thread around here somewhere. But yeah, GE Silicone I Window and Door is good. Most of the other GE products have a fungicide called 'BioSeal' in them. DAP makes an aquarium silicone that is sometimes available at home centers.
Sump Baffles, acrylic vs. glass?

This is a picture of one of my setups without baffles. It's not easy to see, since it's in the cabinet, and it's packed with stuff in there, but maybe you can get the idea. The sump is a 55 gal. all glass tank. Cheap plastic kitchen stools are sitting flat on the bottom of the tank to elevate the media above the water in the sump. The media units are just cheap storage containers that have the bottom cut out, with a piece of egg crate inside to hold the bio media. They are fastened to the stools with nylon bolts to prevent movement. The bio media is SeaChem Pond Matrix. A piece of plastic pond filter sponge type media is layed over the Pond Matrix. One Micron Filter bags prefilter water before it goes over the bio media. To clean the filter, all I have to do is change the bag. They are two of the units in the sump. Each overflow has it own unit. The bio media is part in, and part above the water line. This makes the setup practically silent, with no splashing noises. This setup has been used on this 240gal. tank for almost 5 years now. The tank has 19 adult discus, 40 something Cards, 4 loaches, about a half dozen BN plecos. The tank is capable of handing a bigger load, but the fish need swimming room! This tank also has 2gph drip.
Cool. Marine sumps tend to have baffles because bubbles form much easier in Marine environments than freshwater. Hence why Protein Skimmers are so much more effective in marine than FW. Also because separate areas are useful to separate a refugium, a place for a skimmer, and etc.
