I found this after searching for something completly unrelated and wonder how it would go. It can't be any worse than the test strips which would probably cost me almost the same. I'm still in the process of getting one.
Chemistry And The Aquarium: The Salifert Boron Test Kit Advanced Aquarist | Aquarist Magazine and Blog
The sample needs to have a pH of 7.9-8.3 burn some airation should get a sample to 8.3. What does everyone think, would it work for a pool?Each drop of titrant amounts to 0.5 ppm boron. I could easily match the color to within 2 drops, so the uncertainly of the titration itself is about +/- 0.5 ppm or so. The color continues to change on overshooting the titrant, so it is clear (at least to me) when enough was enough.
The Salifert directions suggest that if the pH is at the high end (above 8.3) or low end (below 8.1) of the acceptable test range for the water sample (7.9 – 8.5), then you can apply a 10% correction to the final value (down for low pH, up for high pH).
