Ok as the title states am I getting ready to build my new sump from a 29g tank. I don't have my skimmer or pump yet but I know which ones I will be getting. The dimensions of the tank are 30l x18.75h x12.25d, will be putting a skimmer that has 12"x8.5" footprint, 6-7.75" operating depth and pump with aprox 5"x3"x5.5" footprint with no piping attached. I have watched some vids on youtube on how to make them so I know how to setup the bubbletrap, What I need to know is how tall do I make the baffles. I do have a little room to set the skimmer on a platform to make that chamber deeper if that helps any. Any suggestions for layout?
