Why are you going with the super pump? The Northstar has more GPM and uses the same electricity. Also, I think you could turnover your pool in 8 hrs with a 3/4 HP Northstar pump. You only need 60 GPM and for the 3/4 HP Northstar that is 55-60 feet of head which is more than your likely to have. So for 50 feet of head, which is more likely, the pump will produce 70 GPM for a turnover of < 7 hours.

Also, I would go with at least 2" pipe if possible as this will increase the flow for a given pump.
