Ok, thanks guys, i think i'll go with the 16 because i just used the score and snap method cause i was just making a lid thing that didn't need to b that precise so the edges r not the straightest. And yea i just used some heat and then bent the acrylic but i need the adhesive to put some sides on. Then i was thinking of jsut stoping at pisces and picking up a bulkhead and just drilling the bottom of the overflow. I'll probably just get two cause if this work then i'll make another one for my sump.The one i have going down to the sump ATM is real ugly. Another questoin i have is, what should i use for a siphon tube? (the clear ones at pisces are fricken $14 each.) or how difficult to build the overflow that doesn't use the tubes, like this one

Thanks, Ian
