And conveniently, I am physics teacher and can totally calculate the flow rate turnover in my pool! YES!!

Sorry to pounce on your thread, but I saw your note. High school or college? I'm looking for someone who can do differential error analysis of pool test & dosing activities -- I'm really tired of various resources that instruct people to add "6.17 lbs of Alkalinity increaser to increase their Total alkalinity by 23 ppm".

I know this sort of instruction is stupid, but I need a big scientific hammer to SQUASH it with. End-to-end DEA of the testing and dosing process IS that sort of hammer, but unfortunately, I lost the ability to do DEA 28 years ago (about 6 months after I learned how!).
