OK, let me dumb this down a little. Would a rheostat cut voltage and there by cut the heat generated by the motor? Or would the motor generate the same heat irregardless?
If so, would running the aerator at 80% possibly reduce heat and allow the motor to run longer without overheating? And, would running the motor at 80% be better for the pond than running it at a 100% for 8 or 10 hours?
I've been planting Caladiums all morning and all this has been running through my head.
