We have an approx. 12,000 gallon pool (+/- 100 gal). We originally were going to go with a VS pump based on their high rating however, since we have such a small pool design, no spa and no water features we decided a good cost cut was to change to a 2 speed pump which should be equally efficient for us. Now the confusing part...which HP? I tried learning on TFP Pool School but to be honest, I am still confused! Do we need a 1HP, 1.5HP or 2HP and why?
To add: This would be for a Hayward TriStar Pump
