I normally use kosher salt and that always worked until I moved to my latest location. I switched to marine salt mix and got about the same hatch rate and thought it was perhaps the eggs. So I ordered a new batch of eggs and got the same resuts.

This proves that we need to be more explicit when talking about marine
salts. I remember once telling folks on the list that it was buffered to a
pH of about 9.4. When someone disagreed with that, I tested a couple of
brands and found that some are buffered high and some are not. For brine
shrimp hatcheries, you want the high pH, so use baking soda if your brand
of salt does not give you that. In most harder water areas, it is not
