The playsand you are referring to was orignally packaged under the name of Southdown who was bought out by Old Castle and then bought by Yardright Tropical Playsand. These were the tropical aragonite playsands out there. The quikcrete is silca based and the jury is still out on whether these add to diatom blooms or not.....some swear by they but if you have sand sifters I wouldn't chance it as silca is sharper edged than reef sands are.
