I'm thinking of replacing my current Juwel heater (i have little faith in it at present) with another Juwel heater (I have tried other brands but they dont fir the internal bracket in the filter box well and tend to vibrate making a lot of noise). Anyway the tank is a 190L but useable water is probably closer to 170L. Should I get another 200W heater or go for a 300W? I'm sure I read somewhere that heater slightly higher specced was worth having? Any idea's ladies and gents?
