We are having our 33 foot above round pool filled this evening. I'm wondering if

1. anyone can advise the best way to start our pool off using the BBB method?
2.I'm assuming I need to order a kit. I'd like to buy the least expensive kit possible - with no frills that I don't need. Just the basics.

Can anyone offer advice for a super-beginner as in, "the water isn't even IN the pool yet"?
thanks,
Kim
