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.

I've had sand dissolve too. Not entirely sure how, but if I had to guess, i would guess just friction from the power heads that stir parts of the sand bed, or me raking the sand bed on occasion or the the wrasses constantly stirring the sand, or all of the above. I've added new sand a couple of times now. I also like taking out old sand because it gets dirty and discoloured.
