Just a simple search 5 - 5lb black or white silica sand for smoking Recepticals same stuff its just sand. for $26 so roughly a $1 a lb at home Depot. Here the link - http://m.homedepot.com/p/Rubbermaid...nd-for-Smoking-Receptacles-UNI-S25/100674209/
But hey u can't beat that. Think about how much that would cost at Petco haha way to much. 25lbs of sand imo is more then enough for a 55. I myself did half pebbles half sand. And I got away with using 15lbs of sand to put a coat over the base pebble. I just like the way it turned out.. Good luck with it
