The only chemicals you need off the bat will be CYA (stabiizer) and liquid chlorine, and a GOOD test kit. (hint hint--> TF-100)
You can buy the chemicals at Lowes or Walmart. The test kit I like is available at tftestkits.net and they offer a "bundle" of equipment you can look at.
A long pole which you attach your brush or net to is necessary. The net and brush themselves are interchangeable on the pole. Also available at Lowes and Walmart.
Will you be manually vacuuming or obtain a robot?
