I need a sanity check here! I'm using the Pool Math app on Android to calculate how much chlorine I need to reach SLAM level. To raise my FC from 1 to 16, using Bleach 10%, it says 207 oz. This means I'm looking for 20.7 oz of active ingredient (sodium hypochlorite), right?
Just for fun, I set the percentage to 100, expecting it to say 20.7 oz. But it doesn't. It says 49 oz. I tried a bunch of values and somewhere around 81% concentration, the "Add XXX oz" starts going up, rather than down, as the percentage goes up. Even at 80% it says 39 oz, which is 31.2 oz of NaClO. Then I checked 1% and got 2119 oz, which is 21.19 of NaClO. In other words... this calculation is all over the place.
Is this a bug in the app? Or does the app use a non-linear calculation because the volume of solution is somehow affected by the concentration?
