Do a 5 gallon water change, you could do less if its easier, I do 5 gallons because I have the water made for me in 5 gallon buckets so I use the whole thing, so whatever works for do and then put the the shrimp back in. You ammonia that's good, then you'll see other levels spike like nitrites and nitrAtes. However I NEVER saw nitrites in any of my cycles.
Im sorry but this is a total waste of money to do a water change during a cycle. I have NEVER done a water change during a cycle because this just delays the process. Why take ammonia out of the water just to put it back in? Just leave it as is and you will be fine. Dont ever change the water till the cycle is over then do a 50% water change and test again, If you levels are still good then go ahead and add fish.
Today my 40g just finished cycling. Took 2 weeks with 3 lbs of live rock and 25 lbs of dry rock, No sand. My nitrates got up to like 70 during the cycle so I did a large water change today and my nitrates are down to ~30. So i will do another water change in 2 days and then add fish.
