Closed on home in Katy, Texas Friday 06-June-2015. Previous homeowner has a pool guy at $40/week. I'm not only thrifty, but as an engineer I build/design/upkeep all my own stuff. TF-100 test kit should be here Monday, and we don't really move in until Wednesday of next week, although I will be doing some maintenance there Monday and Tuesday so I will have pool access. The main question is the Houston area is supposed to get another 6-15" of rain next week. What should I plan for in advance, what chemicals do I need to just have on hand for a situation like this. I like to be prepared. No test numbers will be available until next week.
