I am building a new frag tank that will be 48"w x 24"d x 10"t. I have heard that some large scale frag systems use raceways, and thought I could build a raceway style in a smaller space. The idea is to have baffles direct the flow back and forth across the tank creating a steady and strong flow with no dead spots. From the pic below the water would enter from the lower right corner and drain at the top right. Is this a ridiculus thought, or benificial, please share you thoughts.
