All sand contains debris; fine mineral particles including silica, dust (not silica or mineral), wood and other foreign material. I always wash small quantities, about 2-3 gallons at a time in a 5 gallon bucket. It takes a lot of time and energy to wash sand; I rinse each bucket thoroughly 8-10 or more times.
Sand which I avoid, play ground sand and Home Depot sand for making cement. This is too fine and full of mineral dust; if you wash it 20 times you will never be rid of the dust. When agitated this fine grade sand goes into suspension and clouds aquarium water, clogs the fish tank filters and damages submersible aquarium water pumps by causing excessive abrasion.
Monterey Beach Sand is what I use when I can get it. Yes this was pre-washed but it took all day to rinse.
Some sand comes with the label pre-washed which generally means some of the fine dust has been removed. This is a better choice if available. There is lots of information on the web about various types of sand including: mineral sand created when rocks breakdown, silica sand also used to make computer chips and coral sand.
