Supposedly, my new AG pool will be installed today. Lomart Summer Serenade 18' round, 52" walls, 1 HP Hayward pump, sand filter(not sure of size). The store is doing the install and opening. I will not be home , have to work. My question is , what do I need to do, as far as, testing and keeping water ready to swim in. they will be using my city tap water to fill pool per garden hose. I will be using the BBB method but have no idea what they (pool store) add initially. I have already purchased the Taylor 2006 c test kit. Thank You so much for what you do to help everyone.
