It is a very usefully and valuable process, how to clean the sand through washing with clean water and remove the murky and do the jar test.

[@Grizzlox]

Would this work on fine white beach sand?

[@user-vm7ro1yf1j]

Wait so why are you washing sand?

[@kissingthehomies]

Who knows. Might have an animal that uses the sand.

[@robmcghie5248]

To be used as soil amendment without imbalancing the pH of the soil

[@robmcghie5248]

More interestingly why are you here then. I had to do a google search for how to wash sand

[@bl0odtea]

he could be using the sand for an aquarium, that’s why i’m here

[@arianeparadis6439]

Clean sand is used to filter dirty water for aquarium, pools and even drinking. You have to clean it before you use it as a filter to prevent impurities from staying in the water. You need a clean material to start with. Same thing may be done for rocks and charcoal.
