Yes, I'm a pool store addict. Trying to rehabilitate, since the worse off my pool is, the more money they make! While I'm waiting on a test kit, here's what kind of pump/motor I have:

New (as of this season) 3/4 HP pump - not sure what brand
Hayward S220T sand filter with 250 lbs sand - new filter in 2010, new sand as of Monday

Thanks for your help
