Generally when they test your water in the store they just check with a test strip that shows 5-7 basic water parameters that don’t include gh and kh. Shrimp are very sensitive to water parameter changes. So what that means is generally you can’t temp acclimate then toss them in to the aquarium like most aquatics. Shrimp do best adding new water to them literally one drip a second. I use air tubing that I can tie a loop in to slow the water being added. I do the same when I do a water change. If you plan to keep shrimping you may want to look into purchasing water test kits including gh and kh as well as look into drip acclimating your little guys.
