Hi Bill and V, and Terry Today I'll buy a small bubbler before trying the CLD. What you have described makes perfect sense and is in keeping with my observations, TDS and your comments. When measuring the process readings reflect differently, depending on where I dip the meter, ie, sides of the glass, center, and whether I stirred. If I stir, the reading is higher or lower in some spots. The readings can be seen changing as the meter moves around the glass. Immersing the meter just once with/out stirring does not really give an accurate reading. And should there be more particle at the bottom, the concentration at the surface will also be different.
Last night after reading the suggestions, Terry's included, I made another batch at 30 (without lowering to 13.5). I stop ed while it was still clear. It took approx 45 minutes for 6pmm without seeding (David explained that the reading is actually double if using a TDS) However, there appeared way too much bearding by this time (excessive wearing of of silver electrode) so I think the CLD might be a good idea but the next step is for sure a bubbler. This morning the solution is still clear but the pmm's dropped, (I gave it a good stir) down to 3pmm (6 if doubled). I am using 8 inch 14g silver electrodes. I would ideally like to achieve a clear, stable 10. I must say, one time the importance of electrode position was mentioned briefly but I had no clear understanding of why it was important. I do now. Each time a question is asked that my seem so redundant, something new is discovered by a CS brewer newbie maker like myself who uses a home made generator. I have to do the work and understand this, unlike a store bought machine that will automatically doing this for me. Considering the comments I think spacing is also important, but I am making small batches. I kept the electrodes spacing further apart this time, closer to the side of the glass. Does it make sense that such positioning would increase the time and at what distance does the conductivity or exchange between the electrodes decrease? Based on what V wrote, If I were to use a quart jar instead, I could keep the electrodes closer because the addition of a bubbler would take care of the circulation problem. Yes, It would be so much easier to buy a generator for consistency, but the adventure for me is really in the learning process and making CS clear and with consistent pmm is really a challenge and learning curb. Plus, I know so many people who really can't afford a SG or CMaster so I am eager to learn. Who knows when these devices might be necessary in the not so distant future as emergency kits.

When you stir, the current remains low longer into the process because the concentration is spread out through the entire jar constantly. so the ppm goes up slower between the wires and at the same rate as the entire mass of water is gonig up.
