I have built several acrylic overflows and silicones them into homemade and store bought tanks. There is a trick to doing it, you have to use a plumber primer on all edges of the acrylic. This will give it some texture for the silicone to bond to. You also have to make sure that you get a bead of silicone on every edge of the acrylic that come in contact with the glass.

If you want to see a couple examples look at my 67 gal pred tank & othicx's 200 gal build, both 100% acrylic overflows.
