was that ge I silicone? couldnt really tell from the pics. Hey performance not looks, right? haha, my sump build looked similar with the seals, i figured hey doesnt have to be pretty as long as they stay in place. What thickness glass did you use for the baffles? also, to figure it out with water levels and power outtages, just fill your tank with no return pump on, and when the sump gets to the desired level, thats where you stop filling. no need for equations. then when you turn your pumps on, take a sharpie and mark where it drops to, then that will be your top off level. no more worries about overflowing your sump. Looking real good though, I like the stand and canopy, sorry if you mentiond but what are the dimensions of the tank?
