made a batch of CS appox 3 weeks ago. it was 5PPM tested it again 3 weeks later and it went up to 14 on my hanna meter?? any ideas as to why the PPM went up. its still Crystal C., and has tyndall effect.
And I made some silver a couple of weeks ago using "purified" water from Safeway as they don't sell distilled anymore. It was yellow and only 8ppm but a couple of weeks later it's showing 4ppm.
