Advice on building a tank.

[sphelps]

You could use 6mm, you wouldn't see any deflection from that thickness. I've made a few rimless nanos that are 36 long and 8-10" tall with 6mm. Use 3/8" if you want overkill, but I personally wouldn't spend the extra $, it's a big difference in price.

It's simply a matter of siliconing the glass together. Use masking tape to hold everything together (not clamps) and have a friend help if possible, other wise you'll have to figure out a way to support the first pane as you attached the other ones. You can also use masking tape to define a straight seam and avoid making a mess of it, just remember to remove the tape before the silicone drys. Don't get stressed out over things like fingerprints, excess silicone is easy to clean up when dry, and don't clean up the excess silicone on the outside seams, let it dry and cut it of with a blade.

This was what I was looking for in advice. Why can't I use clamps? I called a glass place for a quote for 6mm and 10mm and they refused to do the 6mm glass. Will try another place and get a quote. also will I be able to cut a hole in the back pain close to one side?

Thanks Chris

With clamps it's easy to over tighten which results insufficient silicone in the joint which can cause many problems like glass against glass which can cause chipping and a weaker seam. Push the seam together so it's tight but not too tight and tape it up. I use clamps for acrylic but never glass.

Strange a place wouldn't sell 6mm, thought it was pretty standard, well it is here anyway.

Ask them to sand the edge when you order it so you don't have to deal with sharp edges and lumps. Unless you get tempered they sand that before tempering.

Any decent glass shop should do the minimal edge work automatically, it should be included in cutting. Maybe just double check when you pick up. I find that some businesses will take advantage of lack of experience and if you ask for what you believe to be an extra service they may charge you for it while others get it for free.

The one place I used for baffles which was Langs Glass in Richmond did prepair the edges without me asking.

I have a rimless tank (48 x 18 x 14 tall) and it's 1/4" glass. It's been full of water for 6 or 7 years, and I bought this tank used. So if you wanted to save some $, it's just a thought. But if you have 3/8", use it. My tank is braceless and has been FULL of rock for most of the time that I've had it. I used it for storing rock and the bottom is a floating bottom.
