[impreza]

hi everyone...
i am in desparate need of some sand. I am too cheap to buy a bag of sand because it is soo damn expensive! anyone have some sand they need to get rid of? It can be anything, doesnt need to be live or anything.
I need about 15 pounds of sand. I only have about 2" and i want at least 4" of sand in my 20gallon. Looking to spend under $15..
please help!!!! anything will do..oolitic aragonite sand preferred..or if anyone has live sand..even better!
Thanks!!
