I have a good amount of coral gravel coming from a salt water tank .
i soak it for a week with water change every day.
but really dont know ifall the salt gone.
i want to use it mix with some gravel to raise my PH /GH /Kh in a particular tank.
if all the salt did not go , am i in trouble if i put shimp or crayfish in this tank ?
Should not be a problem for most shrimp & crays. I know it won't bother the cherries or cajuns. I did an experiment with 2 tsp/gallon sea salt for a couple of months with no issues.
