Was wondering if anyone knew about cutting acrylic and glueing it back? The problem is my sump is too long to fit under my tank, so I'm gonna have to cut off about 8 inches. I don't think we'll have a problem cutting it, but what do I use to glue it back together? Also, does anyone know about drilling a (glass) tank with water and fish already in them? Ihave the HOB overflow boxes, but would really like the drilled look if it could be done with out draining tank. Thanks in advance.
