1) How thick should the glass be on a 180 drilled tank? 1/2 inch? 3/4? Should the bottom glass be thicker?
2) I have read that tempered glass can't be drilled... If this is the case, are 180 AGA/oceanic RR tanks made with regular non-tempered glass on the bottom? Their non-drilled equivalents are made with tempered bottoms...
3) Would a velocity t4 pump 1000gph at 5' head be enough for the return circulation on a 180? What would you guys recommend as additional circulation for the tank?
