There is something wrong with your water.
Use a different test kit.

I wouldn't be so sure of that. The tank is only a month old and the addition of some Amanos caused the same symptoms again. Sounds to me like the filtration isn't able to handle the bioload of the tank quite yet. Since the shrimp recovered once you moved them to an established tank, I think you may have just found your cause.Well... if they are doing fine in the other tank and that tank is using the same tap water, then the problem isn't your water.
Oops, i meant to say the problem is not the tap water. And yeah, even the smallest amount of ammonia can cause problem.I wouldn't be so sure of that.

I'm guessing ammonia or ammonium is the problem. Does your kit test for both ammonia and ammonium? If your pH is below 7 you may not get an ammonia reading and if it doesn't test for ammonium, it may be present if your pH is below 7.
