Great job, but something was wrong with the Hagen kit. I use tons of these and they never fail. When zero ppm, DI or RO water is used the color is white-greenish indicating zero. The test chart is a scale of blue intensities. Clearly green water indicates zero. This can surely be confusing because the test chart shows transparency for zero level, not green.

Also, using Fleet Enema is not the greatest idea. This medication comes in more then one concentration and may be made of more then one ingredient.

I think there are no bad kits, just bad test charts. This is why we need to calibrate the product with known samples. Basically matching the colors with the actual chart.

Thanks for sharing
