we have two pools that are connected by an overflow. I have installed a saltwater generator on the "top" pool (instead of the existing tab chlorinator that was there) so the "lower" pool gets its chorine from water exchange with the "top" pool. This is all handled by a dedicated 0.75 HP pump which is getting long on the tooth and starting to make a fair amount of noise as well as not being particularly energy efficient. Do you have a recommendation for a low speed, quiet pump that would minimize energy costs? I don't mind running the pump 24/7, so that there is good mixing of the water in the 2 pools, but it makes sense to minimize the energy used. Any recommendations would be much appreciated.
