Hi everyone just joined but have been lingering around on this site for awhile now, lots of useful info here!! but any way I just got some small fronts and have them in a forty breeder,and then said heck with it and went and got them a new home,but blah blah blah rite, so on to the point... my 125 that i got is not drilled and i have never drilled a tank,and i have found a site that has what I can tell a good overflow its from glasshole.com does anyone know of them or dealt with them? well any way im in the Rockford area and was wondering if someone could show me how its done as far as drilling the tank? I did my research and the sides of the tank are not tempered..so if anyone has any insight or could help me with if Id be very grateful! thanks
