This is actually misleading. Shrimp may need iodine to promote proper shell developement and aid in moulting but the addition of liq iodine is not needed. Iodine is sorbed by the animals though foods, not the water.
I, of course, have a test kit for ammonia, pH, ites, and ates. Should I also get test kits for alkalinity, calcium, phosphate, and copper? What about the iodine?
Depends on the eventual set up but my prefernece no matter what the tank is to become would always be sure the chem is in order. It can prevent many related problems. You can purchase the copper and PO4
tests but personally I find they are used so rarely, it can be a waste. If your LFS
is generous enough to test these two for you I wouldn't bother. If/when you ever need to use copper as a treatment, then I would definately suggest a proper kit for the type of copper used.
If you intend to add iodine then definately buy the kit. Keep in mind though it will not test for free iodine which can often lead to overdosing. I would still suggest regular water changes instead though. Much safer
