HCA: Hermit Crab Association

Are these two the same thing? I have HBH sea salt. Is that aquarium salt or marine salt?

No. Aquarium Salt is for creating a brackish environment, which is a mix between marine and fresh, and it is salt, not marine salt. Marine salt makes water into the water you see in the ocean. It makes it marine. I've never heard of HBH sea salt, so I'll have to leave your other question to another member

Aquarium salt isn't even good for making brackish - that needs to be mixed using marine salt as well. The only thing aquarium salt is used for is for treating freshwater fish parasites. (And that's a debate in and of itself!)

If you're talking about the HBH hermit crab salt then no, it won't have enough sea-water elements in it to help the crabs long-term. It's also way more expensive then marine mix! Look for brands like Oceanic, Instant Ocean, Kent, or Red Sea in the salt-water fish section.

Thank you so much for the explanation. The amount of salt that it takes to mix this stuff means the bottle goes way fast. So the HBH is not the right one for bathing in anyway....I'm off to get the one of the other ones.
