I am setting up a sump on a 50g reef tank. I have an overflow box and a 25g tank that I will use for the sump. I need to buy some acrylic and a return pump, but don't know what type of pump to use. Any suggestions on the pump or where I can get a good deal on acrylic? (need to have acrylic cut as well). I will just buy the pvc at a hardware store. Any additional suggestions are greatly appreciated.
