If your pool can stay structurally sound during draining, then draining and refilling probably is your best option. Another of our moderators, Poconos, brought up the idea of using a big plastic sheet over your water, adding water from the top as you pump water from the bottom, so that the pool never drains, yet you get a full water exchange. Or...you can always make your conversion now, instead of wasting another swim season! If you'll read through the other posts in this forum, you'll find lots of conversion stories that should help convince you that you're NOT the only one that's ever gotten fed up with an expensive pool that you can't use!
