Time to start drilling some glass holes.

Let me state it clear, I have no idea what I am doing.  I am 100% flying by the seat of my pants.

The setup came with a glass drill bit and some bulk heads, so I suppose I have everything I need to drill some holes in my glass tank.

 For the overflow box and a threaded bulkhead, I purchased them from BulkReefSupply.  They have tons of videos and even chatted with me while I asked basic questions the videos clearly demonstrated.

I placed the overflow box onto the back for some measurements and traced out the drill bit to be sure my holes would have the proper spacing.

I also added duct tape to the front side so no glass shards would fall into the tank (they still did)

To keep things cool, i kept a continuous flow of water on the drill bit, being this was my 1st time, I think it was a success.  Just let the drill do the work, do NOT push down.
