Heater for a 40 gallon tank

[DalPal25]

Hi guys, what wattage should I go with on a 40 gallon cube? any brands I should stay away from? I was thinking of buying the aqueon 150 watt, would that be good enough? Thanks!

150 Watt should be good for a 40G system. Aqueon heaters are ok, I prefer titanium heaters, specifically Finnex.
