Its very interesting that this subject has come up as we were just speaking at length about this.
As far as Equilibrium goes, I do think it would be of benefit as it does contain some of the common elements associated with crustacean growth. However, it does not contain iodide.
Incidentally, it should probably be noted that there is an important difference between iodide and iodine. Iodine is a toxic substance and could be comparable in form to chlorine. In other words, iodine is to chlorine as iodide is to chloride. I'm being terribly simplistic here because I'd rather not diverge to much from the topic. It is simply important to note that the shrimp would be using iodide and not iodine.
Flourish does contain iodide in trace quantities. So, those dosing Flourish would derive some, though minimal, iodide supplementaion. Reef Iodide would certainly add iodide to your system. However, it is probable that iodide reacts in freshwater much as it does in saltwater. In saltwater aquariums, iodide reacts very quickly in the environment converting back and forth between states of iodine, iodide, and iodate. Additionally iodide is pulled out by protein skimmers, binds to the glass and is pulled out by carbon. For this reason, one has to dose very frequently to maintain a standing level. Granted the levels in saltwater are likely much higher than in freshwater. The point is that in order to keep a level in solution, iodide would most likely have to be dosed frequently - almost daily in freshwater as well as saltwater.
We are researching the subject. I think the idea of adding 1 ml to 10 gallons weekly would be good based on what Rob and Phil have seen. This dose, along with Flourish dosing, is probably very beneficial to the shrimp. The Reef Calcium is also an interesting idea as well. We are still studying this aspect in fact.
