Downloaded the app into my phone but it asks what I want to track and I am unfamiliar with the terms CSI, Borates, Flow Rate, Filter Pressure (well sorta on that one) and all I want to do is be able to keep up with my chemistry and know how much of whatever I need to add, but I can't get to a screen where I can put in pH, Alkalinity, CYA, Calcium Hardness, Free and Total Chlorine...and THAT's what I want to do. Can anyone help me get to those screens. Maybe I care about CSI (whatever that is) but I've been dealing with my pool for 14 years and that has never come up.
