I am planning on replacing my pump, pretty sure its too big

[leena]

ive been reading that sometimes the hp can be misleading per pump on what amount of electricity / rpm /watts/amps it actually uses. I don't know much about electricity but can you tell which of these 2 pumps use less electricity on LOW? Im assuming the one that uses the less will be the one that will cost me the least to operate.
