Dan's nano build

Lookin good danny boy. I agree with the unions and 45's. While you have everything apart. Raise the return high enough so you can use some of those screw on pipe holder things to secure the pipe. Loose pipes tend to get broken or pushed places they should not be. I wouldn't stress about the overflow too much. Drilling is superior, but that setup should be fine, just make sure you replace the aqua lifter pump every 6 months or so, if it needs it or not.

I think you can ID tempered glass with a pair of polarized sunglasses. Something about seeing a checkered pattern in the glass, the same effect seen on automobile windows.

Hey Dan, looks pretty good.

I would suggest drilling also, just remember that you don't necessarily need to drill the bottom of the tank since you are doing a peninsula style anyhow (you could easily drill one of the short sides). The sides are less likely to be tempered, and as Snaz suggested you can use polarized sunglasses (or polarizing film) to ID tempered glass.
