Hi Neville,
 
Its not that i have anything against yellow CS. From what i understand, clear 
is just better, as the particle size is smaller. Is there really much of a 
difference between yellow and clear CS?  I do use the "thermal stirrer" that i 
bought from ode. Is that enough stirring power? I was wondering if this could 
be the problem?
 
I will start cleaning the trodes at more regular intervals, and see if it 
helps. Thanks for your help, and any more advise would be greatly appreciated!
 
Thanks to all others who replied as well-
Kenny
