Look at when it started
A new aquarium may develop a temporary bacterial bloom, while disturbed substrate or excess food can also cloud water. The appearance alone does not reveal which cause is present.
Check whether the filter is working and whether the shrimp show distress. Test ammonia and nitrite rather than assuming clear or cloudy water tells the whole story.
Let filtration do its job
Remove obvious decaying food and maintain normal circulation. Avoid repeated full cleanings that strip biological media and create another instability.
Do not use water clarifiers without confirming they are safe for shrimp. If cloudiness persists or animals are affected, gather readings and seek setup-specific help.
For your own tank
Avoid replacing all filter media or performing repeated full cleanings while investigating cloudiness. Remove visible decay, keep circulation running, and test water. If shrimp are active and readings are stable, observe whether the cloudiness settles before intervening further.
