How many watts for a 90gal(heater)

[newfishliny]

I BOUGHT A 250WATT TITANIUM HEATER CALLED PRO HEAT
IS THIS ENOUGH, I am putting it in my sump
I should of ask first then bought

That should be plenty. The pumps and lighting ought to keep the tank warm enough, as long as the room the tank is in is kept decently warm that is. btw, I have read anywhere from 2 to 5 watts of heater per gallon of tank, as a general guide.
