I;d have to go back through my 125g build thread to find the pictures, but it was about $4 something for each 50lb bag. I used 250lbs. I also rinsed the heck out of it, took hours to do. There wasnt much of any residue left. But I will admit it is dirty right out of the bag, I had to really rinse it alot for each batch to run clear.
