Reid - When you have the time, go back overe the postings that Mike Monett gave the list regarding ULVDC, starting on May 8th. He suggests that it is just are well to use a worn out radio battry (9volt) with the system he describes. He does recommend lengthy timeframes for producing CS.
I made a batch of CS over the past 24 hours using fully charged M/H rechargable 9 volt batteries. One batch tested out at 24 ppm and the other tested out at 32 ppm using the Hanna PWT meter. That is using the system with a resistor in-line such as Mike talks about , and running the system 24 hours. Propduction is really slow the later part of the run. CS is clear with no yellow. Dick
