no. if your CS is yellow, you have agglomeration. high PPM will cause this, but that is not the only cause. exposre to emf or magnets, etc can also cause it. the yellow color is made by the particle size, not the PPM.
since i started using a fish aerator in my jar i am not getting any color no matter how strong i make it.
do you have food grade 35% h2o2? put a drop or two of that in and it should break up the particles and the color will go away.
