AquaSoil is great for shrimp. Just beware that it gives of a lot of ammonia for the first month to six weeks of use. If I were you, consider getting it ahead of the tank setup and put it into a 5 gallon bucket. Make sure the bucket is food safe (available for purchase at Lowes). Place it in the bucket and fill with de-chlorinated water. Pour the water off every few days and refill. In a few weeks it will be ready to add to the tank and you won't be fighting an algae bloom like so many do at startup. Best of luck.
