Can i give this sea salt on my hermit crab?

Question

Its Morton Sea Salt. Its said it has no iodide in it, and its from Spain. This is what the ingredients said: Ingredients: Salt, yellow prussiate of soda ( anticaking Agent). that is what it said. So can i give it to my hermits? Please help. P.S. its sodium is 560mg.

Answer 1

It's better to give them aquarium salt. This is salt that when properly mixed with water has the same consistency as ocean water.

I would be worried about giving them anything with anti-caking agents in it.
