Yeah. After following the groups chats and asking some questions and getting 
some replies from some kind people i am finally producing clear slightly amber 
coloured silver colloid. I have been reading around and some people have been 
using a aquarium bubbler to keep the sollution from aglomerating. I have 
adopted the method and works excellent. I am also using distilled water now 
instead of mineral and the solution is allot clearer and less sludge on the 
electrodes. My next step is to build a unit using a 19v powersupply costing 
about $18 whitch can run 3 colloid jugs. One each for silver, copper and zinc. 
I am also going to build a current regulator and maybe pulse it. Im unsure as 
to where it should be astable or bistable. Anyone with ideas. If i can figure 
it out i'll post the circuit. Also anyone got anything else that might be good 
in the circuit. Thanks again all
Take care
