Are you CERTAIN you need that big a pump? HP in pumps isn't useful the way HP is in a car--too much is an expensive-to-run pain in the patoot, that can damage your filter and NOT keep your pool clean.

And get a two-speed! Even if it's got only a manual switch on the pump motor housing it will be worth it's weight in gold!

You'll thank me! It will save you SO much in electricity and be far quieter in Lo mode. You'll use Lo virtually 95% of the time, and only use Hi for your slide (maybe) and your popup cleaners.

I've YET to see a person here with a 2-speed pump who wishes they had a single speed.
