As if you couldn't already tell, I have really played off your design. It's your fault that my tank is going to be so big and I think my wife wants to have a word with you.... So on that note I am also planning on having a full length overflow across the back of the tank. So for this I would add another overflow to the side? This, I guess, would give me the best and longest waves. Also in you picture you show 3 boxes.... Is that what I'll need? I thought it would be one box with 2 extensions. If you use 3 boxes how do you get them to all work together? Also, with the boxes in the overflow, what do you do, just have a hole cut in the glass for the return flow? I assume that this would not need to be sealed, or would it? Also could this "overflow" be just for the waveboxes? Thus keeping the drains in a different overflow?
