Hi! We are official pool owner for the first time! We are so excited for the summer, but I'm a little nervous about all the pool chemicals. I have been reading up on the BBB method and like what I am reading. Being new pool owners we have lots to learn. We have not set it up at this point, but what are the tips for us to do before setting up and once we have the water in. I am planning on ordering the test kit you recommend. Once we have the water in, do we just start right away with the BBB method? Adding bleach right away? Here is the list of items we bought (we bought a used pool).

28ft Round Doughboy Adobe Canyon Pool 2001
2003 Gas-Fired Pool and Spa Heater (Raypak Millivolt) 265,000 BTU
Skim-Line Deluxe Thru-Wall Skimmer
Doughboy Powerline Pump
Zodiac Nature2 Above ground Sanitizer
Sequel II Filter

Based on these products, can anyone tell me what the first step would be once the water is in? Any and all help is greatly apprecaited! Thank you in advance for helping!
