I got some of the lowes playsand. Had to rinse it forever! I mixed it with the sand I already had in there and it looks good, it has a slight pink tinge that is nice and natural looking. I now have about a 2 1/2 to 3 inch bed in the tank I am looking for 3 to 4 inches but I still have sand from mt 10 gallon nano to transplant as well, and it is actually alive!
