    6 to 8 months ago I made up some combined N and P reference solutions. A high reference with 30 ppm N and 2 ppm P (I know the ratio is slightly off) and a low reference solution with 10 ppm N and .5 ppm P that are stored in sealed LDPE containers. They are great at making cheap test kits useable, just test your water and the reference side by side.

    Would there be any reason these solutions might degrade over time enough that the nutrient level would change in them? Besides evaporation of course.

    Should be fine if the bottles are sealed and no evaporation loss.
