Was curious as to how anyone who is like me, and has a separate tank/clearo for each juice (with a lot of juices) identifies them. I started putting small dots of nail polish on them with the same colors on my bottles. Is this crazy? Is there a better way? A marker rubs off the filler bottles and I definitely don't want labels on my tanks/clearos. Thought it'd be interesting to see what anyone else might be doing.
