Just took this out of my 40 gal fresh. Not as fine as sugar but still small like beach sand. has a little bit of crushed coral in it. Will look good for saltwater or reef too. About 45 lbs and a free 5 gallon bucket. Not expecting much since its not live. Spent around $50. Selling for $15. Willing to trade if for saltwater/reef items. Lmk what you have.
