Are there any other overflow kits that are with looking at our is it just glass-holes?
I'd check BRS for a lot but honestly glass holes is all you need. I've bought two kits from him.

Are there any other overflow kits that are with looking at our is it just glass-holes?
Ok so I actually have a question that has to do with this. I just drilled my first tank last night. Drilling went well. I put the bulk heads on, gasket on the inside, tightened the nut on the back of the bulkhead by hand so that i wouldnt crack the glass, but made sure it was as tight as I could get it by hand. Ran all of my pvc, filled it up and bam! Slow leaks around each bulk head. Why am I leaking there when everything seems great? Do you guys also use silicone behind your bulkheads? This seems like a horrible idea but im not sure of any other way to fix this issue? Any help would be greatly appreciated.

Drilling isn't as bad as everyone says. Go slower than you'd like too, and you'll be fine. It took be like 10-15 mins per hole
Did you use a hand drill? I did 5 holes in about ten minutes early this evening.
aI’ve drilled a few holes!
Here are my comments and recommendations about drilling glass. It is very easy once you know what you’re doing. You’re an expert after your first hole.
1. Make sure the glass is not tempered. YOU CANNOT DRILL TEMPERED GLASS. If you are not sure is the glass is tempered, check with the manufacturer or use THIS simple method to determine temper. Don’t simply rely on the labels on the bottom of some tanks….they lie.
With the above method, I use a pair of polarized sunglasses and a netbook computer with Microsoft Word open. Works like a charm….just like in the article.
2. Use a jig to guide the drill bit (or the drill attachment show in the OP video from BRS). The overflow boxes I’ve gotten from Glass-Holes came with drill jig guides. This makes drilling a hole so much easier. If you don’t use a guide, the bit will want to “walk†around the glass. THIS video does show you how to start a hole without a guide (starting the bit at an angle), but the guide makes it sooooo much easier. I make guides out of scrape plexiglass. Here is an example of one of my jigs.
I also use a little plumber’s putty so that now the jig also acts as the reservoir for the water. This gets taped down to the tank. Keep water in the reservoir at all times.
3. Take your time! Let the bit do the cutting. Do not put any pressure on the drill. This is especially true when you are close to breaking through to the other side. If there is pressure on the drill, it will increase the likelihood of small pieces of glass breaking away from the hole.
4. Catch the hole. Put something down on the opposite side of the tank to catch the hole. A folded up towel works great. If you don’t catch the hole, it could break the glass when the hole falls.
It actually is very easy…..happy drilling.
Thanks for the pic. Why two drain holes, just preference? What size plumbing and bulkhead I need to get? Thanks again!!Here's a back view of how I done mine the middle hole is for the return line
