I had a 300W Weipro (model before this: http://www.fish-street.com/weipro_mx1021_300w_ic_heater_for_aquarium_1) on a 200L tank.I use the Eheim Jagers without fail. But, some of mine are getting a bit old and have some condensation inside. I am also looking to buy new ones, the best and long lasting the better, so I am following this thread.
Are the titanium heater all high wattage or can you get smaller wattage for say a 200 L tank?
What are the better brands for Titanium?
