500 Gallon Drain Plumbing

I just took a wood hole cutter the same size as the glass hole cutter and an old piece of scrap wood. Drilled a hole in the wood. Then sanded it out, to make it slightly bigger so the glass hole drill bit would fit in the hole without scraping off all the little diamond bits on it.

Put the wood piece on the tank, ran water on the hole the entire time and started drilling with the glass drilling bit, let the weight of the drill do the work and within about 5-6 minutes there was a hole in the glass.

There's an instructional thread on here that had pictures and instructions. And like I said before, try it out on an old unimportant tank first, I cracked the tank the first time I tried it.

That will work perfectly. Can you tell us how much better it is from removing debris from the bottom of the tank? I've always wondered how much more efficient this design would be.

So far so good. I usually get some junk build up at night after a day of pooping and eating, but usually by morning most of it is gone. I would have annoying amounts of waste on the bottom before the holes, its much better now. I did a water change on Friday and gravel vac'd. As of today, there's just a couple of pieces on the bottom, which should get sucked up eventually.
