Not as thick as you wanted maybe?

Yes, this is the missing detail! The tank is 3-side Starphire and the eurobrace was supposed to be Starphire too, but it's just plain float. It's a beautiful green one-piece polished eurobrace. :(

Regardless, I'm still happy with the tank. It looks great - super sleek.

That's all how I wanted it. There is a 3/4" hole in the middle back of the eurobrace where the return pipe will slide through.
25% right. I think my dark pics threw you off.
That's how it's supposed to be. Though I think I made the gap too big. :o
Me too!
Thickness is fine.

I started off with no teeth on my overflow because it's supposed to pull the water better. All was well for a few months until some of the smaller fish found out it was a water slide! I was pulling fish out of my overflow or sump every day. Beautiful looking tank BTW!

Yeah. I'm pretty sure I will have this problem too. It is 1/2" gap and I think I should have done 5/16". That was my spec though, not Dave's. I think I will add a bit to the top part to make the gap smaller.

Lovin the new tank Mindy

For your overflow ...
You could silicone some small glass strips inside the box - one set for spacers and slightly thicker than the acrylic you'll use, and a second set to hold a sheet of acrylic with teeth cut out of it. Then you just slide your acrylic up and out of the box for cleaning.

I realize you'll lose some of the weir effect, but it'll keep your critters where they belong.

Or you could get inventive and design a mesh 'box' to cover 'some part' of the weir.

New idea ...

Vertical strips of glass on the left and right ends of the weir say 1/4" thick. These keep the weir running 100% as they will space the acrylic 1/4" away from the back glass (inside the overflow).
Next is some strips @ 90 degrees to the first strips. These hold the ends of the tooth sheet.
And lastly is some vertical strips @ 90 degrees to the second strips. These hold the tooth sheet in place against the second set of strips.

I like this idea so much I'm going to incorporate it into my upcoming build.

I'll try to post a drawing later today
Right now I have a brake job to do

My dream tank would have a weir. They look so stealth:)
