Also make sure if you are using aligator clips that these clips do not touch the water. ( i have seen someone doing this ) They were using the right water and the right silver but letting the clips actually sit in the water causing the metal itself to erode into the batch. ( they were rusted even ) That I concluded was teh reason the batches were all cloudy.
When I put them out of the water and made a sort of bridge- everything was fine and turned a pale yellow color.
