wattage of heater?

[Everett Adams]

setting up a 120 gallon sw tank

tank came with a hydor 400w heater

I'm thinking that's not enough though, and advice would be appreciated

I only use 150w and 250w heaters in my tanks, even the 125g's. BUT I live in Florida so I don't have huge temperature swings. I would think that 400w will be more than enough for a 120g.
