Carol Ann, The current is critical with making LVDC CS. If your power supply is unregulated it will continue to 'ramp up' the current as the conduction factor increases with the increase of CS %age. The best CS gen's are those which have a current limiter to hold the current to 1ma or less. Yours will provide up to 1000 times this (even though it may never reach that point). The increase in current is taking 'bigger bites' of the silver electrode without helping your actual CS. It is like taking a pinch of sand and adding it to a bucket of water to make 'good' CS or, with the larger current you are taking a handful and dumping it into the bucket. Some of the handful will add to the CS but the 'clump' will fall to the bottom and be wasted. By reducing the current your production time will increase but the CS should remain clear or very nearly so no matter what %age you reach. You can add a CLD to your device easily since you are not using a 'manufactured' one. The instructions are in the archives and help is available here whenever you ask. Best Wishes, Bill Keen

I have experimented my process beginning at 30 and when the solution reaches 1 or 2 ppm I switch to 13.5. Eventually, regardless of where I begin, I finish with a settled solution which is not clear. The end product is always some shade of yellow. Also, it may read 10-12 when I am done, but eventually settles anywhere from 3-6 as a finished products days later and always the color deepens. Do you think the Adapter using 1000mA is too high?
