What size is your pool? Do you have the cartridge filter or sand filter? Did you get the Intex SWCG? If you have the cartridge filter, go ahead and order 2 or 3 of the GOOD cartridges referenced here, http://pool9.net/ssr/ , unless you like cloudy water and very fine "stuff" on the pool floor (this is the voice of experience). If you have the SWCG, you "probably" want to disconnect the copper ionizer. Copper turns blonde hair green, stains liners, and will eventually make your water the color of the Statue of Liberty.

Enjoy your new pool!
