What would be a good heater combination for a 120 gallon tank? Two 300 watt or two 400? The tank is 72x18 inches. Thanks!

Two 300s should be fine -- put them on opposite sides of the tank and you'll get nice heat distribution.

i agree, that sounds best to put 2 heaters in opposite ends. What are you doing for filtration on it?

I hadn't thought of that, but if you're using a canister filter, you can get in-line heaters that heat the water as it returns to the tank: http://www.drsfostersmith.com/produc...9&pcatid=11369

Thanks for the input!! I have an Eheim canister filter, so I might take a look at an in-line heater. I am wishing now I would have bought the filter with the heater attached, but oh well. I have a 300 heater that was a gift so the budget reality is I will probably pick up another. DUMB BUDGETS!!!!!!
