lesson for the day... when cutting glass be sure its not tempered glass and if your not sure dont try and snap it on your living room rug. 
 
was making a skimer shelf for the 50g tanks sump. took apart a cheap 10g tank for its glass measured, used glass cutter, tried to snap didnt want to to i put more pressure.. still not (at this point  oneshoudl begin to wonder) hitit really hard and tiny glass pieces all over. 
 
so just because its a cheap tank its not necesarily plate glass.....opps
