So, I got a 90G glass aquarium from craigslist, confirmed the bottom isn't tempered and am looking to put in an overflow (weir type) and am wondering on location of the box and the holes drilled.
I've seen over flows in the center on the corners and wondered which is better/more visually appealing. I have a 75 with a 6" overflow in the corner and seems to be alright but I was going to make this one a little bigger to accommodate more water flow and thought that might take too much away from that side.
Then I thought what if I make a longer but thinner box along the back wall. For this, I was wondering what the minimum distance from the edge for drilling a 1.75" hole (glass) and what is the minimum distance b/n holes would be as I'll be drilling 3 (or 4) holes for bulkheads. I'm finding all kinds of conflicting information.
Also, when you say how far from the edge and other holes are you talking center of hole to edge of glass or edge of hole to edge of glass, edge of hole to edge of hole?
Thanks
