I have used store bought blue and white sand. I would like to use natural colored sand. I would like to take sone from a lake. I have got some ideas how to clean it. 1. boil the sand 2. Bleach or chlorine wait 24 hours for chlorine to evaporate then rinse very well. 3. Boil then run through R/O system to remove any polution. any feed back would be great.
