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.
