Just make sure if you choose to use acrylic for the baffles that you don't cut the acrylic to the exact same dimensions as the ID (internal dimensions) of the tank. Acrylic absorbs water and expands slightly. Extruded acrylic, which is cheaper than cast acrylic, expands more than cast acrylic. If you wedge a piece of acrylic into the sump to act as a baffle and over time it starts to absorb water and swells you can imagine what it could do to the sides of your sump.
Personally I'd just go to a place like Speedy Glass and have them cut some 1/4" glass to the dimensions you need. It shouldn't cost much at all and will, in all likelihood, be cheaper than acrylic. Plus it will bond better than the acrylic would with silicone.
