Hi, again, Jack,
Well, the 1hp pump would save a little energy cost but I don't think it would clear your pool.
99% of water clarity issues on this forum are from a lack of chlorine. I am guessing that is your issue, too.
The only way we can do anything but guess at your problem is to post a full set of test results.

If those don't make sense, post back and we'll get you some explanations.
