We have never had a pool before and I would like to do it right, especially since my husband has put me in charge of this project. This site helped us a great deal when it came to picking out what we needed. I go to Pool School in the morning and I want to be prepared. What is my next step and what do I need to buy? Our pool holds 21,000 gallons and we have a sand filter(not turned on yet). We bought the Taylor K-2006 test kit and we filled our pool with municipal water. We tested the water this evening:

PH 7.5
Alk 90ppm
No Chlorine

What do I have to do next in order to swim this weekend? Nothing has been added yet.
