I made my own sump from a 55 gallon tank, it's pretty easy. I used acetone to clean the glass really well, then put the baffles in and used masking tape to hold them in place. I used ge scs1000 silicone and applied a generous bead then let it set for 2 weeks. To make the bubble trap in mine I used dvd cases as spacers, and did one baffle per day so i could easily take the spacers out. Good luck with the project
