Okay i am going to build a external overflow, out of glass this weekend, how big should this be on a 16" back
i was thinking 8"X5"X10" (LxWXH) with 2 1" bulkheads
as for the closed loop, i am still reading on what that is
and how to build it, that way i know where to drill the returns
as for notching the back, just use a glass cutter and go nuts or should i take it to my local glass shop and get them to cut it?
