I may be asking something that everyone knows about but I am new to discos, right here goes,as I look at my disco with bonnet up, on the right side is a bottle with 2x black caps,what are they for ,and whilst you are there should the fluid in there constantly circulate at high speed, it looks like a vortex. any ideas.
