I've read the primer , and my local discount store stocks Mystic White, but it does not (to my thinking) clearly indicate on the bag what the size of the granules are. I think maybe this is the .80mm based on the "80" on the side. Is that right?
Even the HTH sand that is repeatedly mentioned here in the forums doesn't indicate if it's #20 .40-.55mm sand or not.
