all of this is great info. but something I wonder about, that I havent seen. is how much of this stuff do I need to have for a new pool owner. My pool is going up thursday, so obviously i dont know what the water will be, but I would like to have on hand what I am going to need. So how much bleach is a good starting point, 1 gal. 5 gal. etc... How much baking soda, borax??? I know everyones water is different. and the test kit is on order.
