Hello Frank and everyone, For a while I used calcium carbonate to adjust fairly pure water to optimal conductivity. The tap water here is highly variably because it is a blend of surface water and deep well(s) water from limestone strata. I put water of 350 PPM TDS through 30 micron > 1 Micron > carbon > RO > atmospheric still; yielding about 0.4 micro Siemens. According to Bruce Marx, his HV process works optimally with a start water of about 0..8 PPM, or 1.5 micro Siemens with the calibration of my meter. I mixed a batch of calcium carbonate about as strong as I could get it---don't remember the conductivity---and used that to adjust the conductivity to 1.5 mS. That method much more frequently produced a turbid yellow-tan sol. Similar effect with baking soda. Tap water works much better, but I constantly must adjust the addition because the water is variable, even when stored.
The concentration at which the fog would form was quite abrupt, and would unpredictably happen in the last 15 minutes of a long run---about 2.5 hrs. This without temperature control during process, but from a consistent start temp of 75 F, +/- 0.5 or better. The effect, though very discouraging, was quite beautiful; 3-D scroll-like long horizontal turbinate clouds forming in the convection currents. They are relatively stable if you do not disturb the vessel after completion. An off point question: why does calcium carbonate dissolve so slowly? Over months, a saturate solution-with a bit of solids still on the bottom of the bottle---will slowly rise in TDS. Why does it not just go up to point of saturation? This is in a nearly full and tightly capped glass bottle. To not clutter, thanks in advance.

I do not make DC sols and from the perspective of technical purity do not recommend the use of salt. Therefore, the following is offered only for informational value. Any salt not containing chloride would increase conductivity thus speed up cs production. Sodium carbonate and sodium bicarbonate will work fine and not contribute chloride. Sodium citrate should likewise work fine. Sodium bicarbonate is what CSPro Systems uses. No chloride, so no silver chloride. There are many salts that do not contain chloride since a salt is a metal and an acid. It is probably best to avoid salts containing nitrate for obvious reasons. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
