So I have taken down a 240G marine aquarium with my sights set on converting it over to a Frontosa tank. I have about 250 lbs. of live sand and I want to use it as the substrate for the new set up. Does any one have a method I could use to wash this sand? It is very fine and in a collander I will lose to much of it. I actually thought about drying it out on a tarp outdoors to kill the marine organisms. Any thoughts out there?
