Sk187 I do not have an answer for you and am interested in the answers you are getting as much as you are.
But one suggestion or at least question I would raise is the possibility of using a different pump. Could it be possible you could use a lower capacity pump (for example a half or 3/4 horsepower pump), cut your electricity bill enough to pay for the pump in a matter of reasonable time, and run the pump longer hours.
I don't know. Not even suggesting it. Simply raising the question of running a smaller pump continuously or a large pump for only a few hours.
In other words would running your big pump for say 4 hours per day be preferable or running a smaller pump 24-7 (with resulting similar electric costs)? I don't know and will be interested to hear the answers of those that do.
