Since there are no animals in the QT
(I hope), water changes will not be needed during the cycle process. A 10 gal
tank will not need a very large piece of shrimp to spur the cycle, so the larger it is, the more ammonia you will get.
The shrimp should not be removed until you see a natural reduction in ammonia and nitrates have formed as well. Once the ammonia has fallen a fair amount, you can dispose of the shrimp. Just be sure to add small amounts of food a few times a week to feed the bacteria while the cycle finishes.
What type of filter did you choose and did you seed it?
