i used sand from the lake at my cottage for my 150 gallon tank you dont need to do much to sterilize it i figure the chlorine/chloramine in tap water would get all the nasties i just rinsed it real well in a big tub with the garden hose and put it in my tank no issues so far
the lake is spring fed so its very pure no limestone or anything bad in the sand just very high in iron
