Without wishing to make more of this than it deserves, I have used the AE trace and at one point was dosing at double rate. This I am fairly sure killed most of the shrimp in my EI nano. I have since added several from my other tanks and reduced the dose rate to as per the AE website and they have not lasted more than a few weeks, compared to over a year in some cases in my other tanks which dont get the regular trace. Now this could be due to the move, but it seems to much of a coincidence. I also noticed a few of the new additions doing the whole 'crazy jerk' thing which is a classic sign of poisoning. I have now switched to tropica plant nutrition, in the hope that the shrimp survive a bit longer, then aren't cheap after all.
That said, as far as trace ferts go the AE dry mix is very good and cheap and I shall continue to use it on my lower light tanks that don't need such a high trace dose rate. Perhaps its just not for shrimp tanks.
