not really.

As said, i only do the molarity check every few months when i feel like  
it, 'cause i just add stuff by color and etching speed. I don't understand  
anything about chemistry, and how i described it is how i imagine it, i'm  
not sure it is chemically correct, but it is a theory that explains what  
is happening so it's good enough for me.
You can do it easily if you want.
