Does anyone know of a test for Borates other that test strips? Based on recommendation I saw here, it seemed the best choice was the Lamotte test strips, which is what I am using. However, I have a very difficult time distinguishing the difference between 30-50-80 ppm. I can see the difference on the compare strip on the side of the bottle, but my test strip never seems to match one of the colors exactly and I can't really tell whether I am at 30ppm, 80pppm or somewhere in between. I am not color blind, but the various shades of pink it is supposed to be are very difficult for me to see differences.
