I SO understand you being intimidated! I ordered the test kit BEFORE I ordered the pool to make sure I could do it!!
Please go ahead and order it when you have a chance today. We have videos and I can walk you through the tests! They will take a few extra mins the first few times but once you have done them a couple of times you will get up the speed.
Are the kids up yet??? I bet they are watching the windows and listening for the sound of the trucks!!!
