well it is going to be a sump/fuge so I am adding the baffles to seperate the sections more then anything. Will be using three over-under-over for the skimmer section and just one for the fuge part.

Called around town here and got a price for the sup/fuge of $47.00 for all the pieces 1 25 1/4"X14 1/4" two 26"X16" and two 16X14 1/4" all 3/8" thick. Once built I will measure and get the beffles cut to about 1/16" small and silicone those in as well. For acrylic it would have cost me $93.00 plus the drive to SA plus the weldon. I don't think I will have any problems with glass but I will build and let dry 72 hours before water testing. WIll keep everyone updated but may be the end of the month before I start. Thanks for everyones input.
