I run 3 stealth 250s on my 220,one in each overflow and one beside the one over flow box.If your sump is glass or acrylic you can put on in the sump.

It depends on the room temperature and the desired temperature of the water. In a 75 degree room, you don't need much wattage to keep the tank at 78 degrees. In a 65 degree room, you need a lot of wattage to keep the tank at 80 degrees. A good rule of thumb is 5 watts per gallon to keep the tank 10 degrees above room temperature. Since big tanks hold water temperature better than small tanks, you can get away with less. I run 2 300watt heaters on my 125 (4.8 watts per gallon).
