The WFDS-26 is a 1.5 HP up rated pump and it would be too big for your pool. The pump I was suggesting was the WFDS-24 or WFDS-3 which are really the same pump. If you want a 230v pump, I would suggest the Superflo 1 HP up rated pump. It is a smaller pump than the Whisperflo but I don't think you need a big pump anyway.

At $0.11/kwh, it will take a long time to make up the difference in price. I estimate it will take about 160 months of one turnover/day in order for the Intelliflo to start being more cost effective than the Whisperflo so the Whisperflo will probably have a lower lifetime cost.
