Ok, I am new to the site and new to the bbb method. Just received my tf100 test kit and am hoping for a couple pointers to get going. Am currently without normal internet so not sure if pool calculator working right with Droid phone. My readings I got are: cl&br basically zero as wanted to wait til got kit plus couple storms last week. TA-80, CH 250, PH, 7.8, CYA 20. 13,500 gallon round above ground(24'x4'). What said to add is 112 oz bleach, 96oz stabilizer(bleach again??), 63oz of baking soda and 11 oz of muriatic acid. First question, do I really need the muriatic? Then second is the calculator relatively accurate when using then droid phones? Sorry if covered elsewhere, but my net access is a joke on the phone. Thanks much for any/all help. Would have more chlorine but wanted to wait after storms to get the kit, so I knew that would be low/nonexistent.
