And for filtration... the AC30 is quiter than the AC20. Since the flow is adjustable, it'd likely be a better buy if it's just a few more bucks.
this just isnt correct it all depends on the wattage and the quality of the heater. there are heat pads that do work just gotta look into other fields such as keeping reptiles or growing seedlings its all depending on the wattage and the temp vs ambient temp. you could have a good tube heater not work due to it being out of range but that doesnt say that it doesnt work ya know?
