I think I almost made a Mistake!!!!

I purchased my first ever pool today. It is a 24 foot with a 2hp 2 speed and 150 sand filter. The place that sold me the pool also sold me on the AQUA-stuff...After reading this site I now realize that I made a mistake...They are coming to install the pool on Monday. Can someone please help me with what I need to go and buy, how much and how i get started on a new pool....

Thanks in advance,

mark
