| they aren't the same thing and they are used for different purposes. epsom salts act as a laxative to clean out the fish's system and can keep them calm when stressed out.
i think pond salt is basically pickling salt (non iodized salt) which i just buy from the grocery store. you can use sea salt they use for marine tanks but that would be a waste of money. i'm not sure about the sea salt they sell at grocery stores, mite contain some unwanted chemicals. |
