Ask for current measurements and which tests or meters were used, without assuming they are exact lab results.

Why seller water information matters

A shrimp's recent water conditions help you plan a cautious introduction to your aquarium. In a shrimp-focused aquarium, the choice should also support steady routines, visible livestock, and access for basic care.

Before you act, check which parameters the seller measured and when the readings were taken. Compare the item with the rest of the setup and note any recent change that could affect what you are seeing.

A careful way to proceed

record the reply and compare it with your tank before opening the shipment. Make one adjustment at a time and watch how the aquarium responds during normal observation.

Avoid treating an old or unverified reading as a guaranteed profile. Labels, products, and tank conditions differ, so use a reliable guide as context and record what you directly observe. If uncertainty remains, ask an experienced shrimp keeper before making a consequential change.
