Ill re-rinse the sand out for you in the meantime, but yea, any evening or over this weekend will be fine, ill be home with my boy while mom is at work, so we usually just kill it at home on those weekends. The sand has been sitting without aeration for over a week now, but its already been rinsed out, ready for a new tank (may want to rinse once again before putting in the tank). I can also provide you a scoop of live sand in a baggie or something, but you would want to keep that aerated in fresh saltwater until you need it to seed the stuff i have to give away.
