I have cut down three tanks for use in sump, ato and frag tank. I did however use a simple glass cutter, snap into tank pane by pane after cutting silicone out to cut height.

Cutting with a wet saw will most certainly cut glass. However by hand on a four foot long pane you will probably get 75-90% of the way through then it will most likely break. Why I suggested scoring it prior. An initial score may keep a break controlled. It may not. But for a sump to reuse a tank you already have, sure give it a shot if you want. I can't promise you won't break it, and a good chance you will but it's your tank, have fun with it if you want. Even a grinder with a dry diamond blade can cut a tank in half. Just play safe. I'm sure I don't need to tell you glass is sharp.
