We have an Elma Transonic Digital machine which has a tank about 
18"x12"x12" and we put just about every disc that gets transfered in it 
first, On really grungy discs you can see the stuff coming out of the 
grooves like little streams of smoke in the water. There is an additive in 
the water, Cetramide, which I think (may be wrong) precipitates the grunge 
out to the bottom of the tank. The second stage is a modified Keith Monks 
cleaning machine where the suck-up arm has been attached to a rather more 
powerful vacum than the original fish tank style pump. It is just there to 
suck the water from the ultrasonic tank away
