Drilling thick glass

Awsome, I didn't know that....I'm planning on a Beananimal style 3 tube overflow system is supposed to be dead silent and the 3rd line is an emergency drain. I like the redundancy of it too.

Line 1 is a full siphon
Line 2 is an open standpipe unless something happens to Line 1 then will become a full siphon
Line 3 is the failsafe line and if everything goes right will never see water.

The ends of all pipes come out under the water line of the sump so no splashing and no sound from that.

 

If you saw my build thread on my bow front canopy then you know there will be lots of pictures ;D

Thanks for all the help everyone K+ to you all.
