Is there a printable chart somewhere that tells the increase of FC levels based on how much bleach you add? Perhaps I am lazy, but it's a long way out to the pool, and I have to walk back in to plug my numbers into the Pool Calculator, and go back out to add bleach. I have a dumb phone, so I cannot use an app to carry it out with me. I'd like to be able to print something out, laminate it, and keep it with my test kit. I've searched the site, but cannot find one.
