Does anyone know how much I should subtract from the glass pane dimensions for the silicone layer?

I want to build my own Aquarium and order glass with the dimensions I need. However, I do not know if I should subtract anything for the thickness of the silicone layer.

For my sump the esthetics are less important and I plan to subtract 1 mm from the with of the dividers.

I've attached some pictures of my project in this post.

Any of you help and suggestions are welcome.

Thank you.

The actual silicone layer is going to be paper thin if done right. For a small project like this I would buy actual aquarium silicone instead of the GE stuff.

To further what @GraphicGr8s said, it seems counterintuitive to use such a thin layer of silicon, but it's actually much stronger than if you use a thick layer. You end up with more flex and more pressure on the silicon if you make it too thick, and it will fail more easily.

What many fail to account for is the thickness of the glass when cutting the side panels.

Joey is always good for a tip or two.

@GraphicGr8s and @natemcnutty,

Thank you for your swift reply. Very helpful.

I will assume the effect of the silicone layer is negligible and obviously I'll subtract the thickness of the glass at the corners where necessary. I plan to use 1 mm (0.5 mm each side) for the dividers such that I can place the dividers and inject the silicone when the outside panels are already in place.

Time to order the glass :)

Thanks!

Rik
