I simply put in new juice and mix it with whatever juice I have remaining when refilling the vivi nova. Sometimes the remaining juice is darker than fresh juice but I mix them anyway since it's so much easier. I only clean my clearo every four or five tanks. I cannot stand cleaning every tank.
Or are you supposed to waste the remaining juice and always start with a fresh new tankful?
