In pratical terms it means that the silver particles aggregate together. Basically you can tell particle size by what what light is absorbs. Ionic silver (atoms) absorb in the uv range and will appear clear when in water. As more atoms bind together, the wavelenth that is absorbed increases so that at around 5 nm or so it will begin absorbing within the visible spectrum, ie. violet. When violet light is absorbed, you see the complement, or in this case yellow. Thus as particle size increases the "color" of colloidal silver will go from clear to light yellow, to gold, orange, red, and brown. When you have a range of large particles the it will absorb light across the band, and will appear grey or black. Large particles will not stay suspended and will precipite out, that is fall out. This is bad.
Thus when you add aloe vera and get the grey, you end up with a small amount of large particles instead of a large amount of small particles. Effectiveness is proportional to the number of particles, so this drops effectiveness considerably. Also if you ingest it, the large particles will not be able to penetrate the stomach and make it into the blood. Keeping the mixture at a ph of 7 or more (sorry I said 7 or less before, that was wrong) and refrigerating the combination should allow it to keep for several months provided that you start with a high quality colloid that is clear, or only faintly yellow and refrigerate it. BTW, many sources of aloe vera have benzoic acid in them, and this tends to make the silver aggrregate and precipitate as well, so try to get pure aloe vera if you can. I hope this helps.
