Tetra Marin Aquarium Salt Tetra Marin Salt 400g

This is 400g of marine salt for saltwater fish and invertebrates. It is labeled by a pet shop as for 10 liters. Although it was unopened, it appears to have absorbed moisture during long-term storage and is quite damp. Please purchase if you believe it can still be used without issue.
It will be sent in a plastic bag via Yu-Packet mini.
