How do I mix an iodine dip?

[Just John]

I hear a lot about doing iodine dips and that drugstore iodine can be used, but how much do I mix and how long should I dip for? (I am particularly interested in dipping sickly zoas.)

You might try posting in one of the reef forums or the chemistry forum. One thing I can tell you is that some iodine solutions contain surfactants, like povidone. You can’t use those. The typical solution is called Lugol’s solution.
