Depending on your water chemistry and type of sand, yes. I would guess I have had about 2 to 4 pounds out of a 40 pound bag dissolve in the last year, and since I don't vacuum I am pretty sure it is from a chemical process. I am hoping when I get my refugium set up with a light on an opposite cycle it won't be as bad.
