I was browsing for heaters online, I've noticed that Visi-Therm are very cheap, according to prices. Why? What makes them so cheap? Rena Cal heaters at PetsMart are so much more expensive and its the one I'm currently using and am very happy with it. I am shopping for a heater for the 55gal tank. I'm trying to decide, take the risk for Visi-Therm or go comfortably with Rena Cal.
Oh, another thing, should I get two (divide up the wattage) heaters to ensure both sides have proper warmth, or just get one?
If I am not mistaken, for a 55gal, it will be a total of 300w?
