"...And don't let those reef
guys talk you into adding iodine to your water. You
have plenty if you're adding a commercial trace
fertilizer or if you are feeding with a commercially
prepared food."

This came as a surprise to me, because, as a result of a recent posting in
the APD, I had been throwing in 1/4 tsp. table salt (which contains
iodine) every week. My understanding was that, like us, the shrimp need
only a trace of iodine.

I don't see any mention of iodine/iodide in the listing for Tropica Master
Grow.  Nor do I find it mentioned in the ingredients listed for Tetramin
flakes.  Please elaborate.  Thanks.
