Unknown ... sand generally falls into two broad catergories .. calcium carbonate and silica based. Easy way to test is to take a small sample and place in a suitable container .. add some vinegar .. if it bubbles and starts to disolve its calcium carbonate .. if not then it silica.

It was probably Southdown or Oldcastle Playsand. As long as it is coral-based, it's OK to use in a SW tank
