Whats best? Submersible Pumps or External Pumps? Submersible pumps are way cheaper than the External pumps so theres gotta be some kinda reason for it. Are the external pumps quieter? The only advantage i see is heat transfer from Submersible pumps isn't a factor on External. Any other reasons?
Also, who makes the best pump?
