okay so i went to kailua beach and scooped up some of the clean sand near the "dune" area and now i wonder how the heck im gonna go about putting it into my fresh water tanks...
how would i neutralize this sand of its salt/salinity in order to make it safe for my freshwater monsters?
All sand and gravel needs to washed to get rid of impurities.
Sewage is 98% water anyway and is easily washed away.
That sand has also been exposed to the elements for months also.
Wash it well and use it.
