Sorry..I had a typo--I meant to write 150#, not 15#. Good luck with it! Just remember it's better to oversize your filter than your pump, especially sand filters. I can't think of any reason to have more than a 3/4 hp pump for a 10k pool unless you're going for a 2 speed you intend to run on LOW. If I were doing it all over again, I'd get the same pump but get a 250# or 300# sand filter. BTW, my sand is the original sand...sand works better as it gets older.
