What would you say the benefit is of using new sand rather than giving the old sand a heavy rinse and using it again?
Anyone who can answer tis feel free.

Also to the op, if you would like I will open a new thread with my questions so I am not hijacking yours.

I have wash out sand & reused several time with no issues. I used a large fine fish net, 2 - 3 cups at a time rinsed under the tap until water was clean.

When switching tanks I try to remove all the rock I can WITHOUT stirring up the sand to a big tub with tank water in it first, then remove all the tank residence to another large tub or 2 with tank water. Next remove as much water as possible still WITHOUT stirring up the sand. Once I get to the point that I have no choice to stir up the sand all the remaining water goes down the drain. Finally I remove all the sand to a bucket to wash THOROUGHLY. Before returning any rock to the tank I mix up a new tub of fresh SW & rinse the rock in it removing any loose debris.
