Okay I am in the process of plumbing in a refugium and will need more sand for it. I am going to my LFS
and buying some along with some Calupera. Everyone would agree that you do not use the water from the LFS
in your tank, but I have not heard about the sand. You would naturally have LFS
water in the LS
it can't be totally dry. Would that be a problem or am I thinking too much?
