a bit off topic but perhaps you can help me.
I want to build an acrylic box for a dsb to fit on top of my sump but so far I have been unable to get decent supplier of acrylic. Homebase and the like sell thin acrylic sheets (couple of mm) which is not up to the job. I would like to use 10 mm sheets.
As you are building your overflow box with acrylic perhaps you can suggest a supplier?
