First off, let me say this forum is a great resource.

We are getting our pool setup next week and the family is pretty excited. We've had those small 10' soft side pools with the blowup rings on top before and just bought the chemicals and all from wal-mart. I have a little smidge, not much, experience with pools. Since the new pool is a lot bigger and 'permanent' I have a few questions about setup.

Here is the pool info: 18' AG round pool ~7,200 gallons. We are on city water.

1. If I'm starting out, should I go the BBB route? What would be the disadvantage, if any, going this route?
2. Where do you buy baking soda and all in bulk; Costco, Walmart? (can't say I've ever seen it in any size but the little boxes)
3. Can the kids swim in it after filling or do I need to chlorinate and get things setup first?

I'm sure there will be more, but that's about all I can think of now.
