lousybreed said:a small power filter will not keep a 5 gallon tank warm. Those filters use at best 10watts. Even if 25% of that energy transfers into heat that goes into the aquarium (a big strech) this is only 2.5 watts. This isn't even enough heat to keep a 20 oz soda at 80F with an ambient temperature of 68F!!!!! Then when you factor in the evaporative cooling caused by flowing water, you might actually get a decrease in temperature!!!! But a $10 heater and read up about fish!!!!!!!!!!!
