I seriously doubt you will need that much. With all the lights you plan on using on your tank I bet you could get away with 1000 watts of heat total. With pumps,lights,etc....running I seriously doubt the heaters would come on much.
Me personally Im using 5-200watt stealth heaters controlled by my AC3. Those heaters are cheap to replace and have been pretty dependable for me over the years. I like multiple small heaters in my tanks which keeps me from worrying about my tank getting boiled if a heater sticks on.
