How to make seawater saltwater for your Hermit Crabs

I got my wife a few Hermit Crabs, they need and love saltwater or as it its called seawater. We tried the pet store version, but at $5 a small bottle it was way too much.

This is how to make your own seawater for a fraction of the cost.

The formula is 1.23 Oz  of coarse sea salt added to 34 Oz of fresh water.
