You'll do fine with the kit. After a couple of times, you'll be pros.

Go ahead and add some bleach in there or you'll have a green pool by the time your pump arrives on Wed. I'd suggest adding 3 gallons of 6% bleach each morning and each evening. That will add just over 8ppm of chlorine to the pool. Pour it in slowly around the perimeter of the pool as far away from the edge as you can reach. Then, take a clean broom, oar or something and stir it around as much as possible. Hopefully that will be enough to keep algae at bay until you get the pump hooked up and running. Keep us posted.
