i am in the process of tearing down an old tank and setting up a new one. i understand that aragonite sand has the ability to actually ABSORB phosphate and other pollutants. i would like to reuse some of this old sand, but i presume that simply washing it will not remove the unwanted PO4 that it contains.
so, do you have any suggestions for other treatments that i might apply to clean up this sand?
