Re-use old sand

[banzai75x]

My friend is giving me some old sand. He took it out of his tank a few months ago, and left it in a bucket completely dry. It used to be southdown mixed with some live sand at the time.

Should I use this sand? If so, how do I clean it?

I dont see why you cant use the sand. One thing I would do is take it out of the bucket and put it someplace and spread it out so the sand can get air around it for a few days.

Should I wash it with anything? cold/warm tap water or RO water?

Where has the sand been? Did the bucket have a lid? Any chance the sand could have gotten any chemicls in it or pesticides used around it?

If I were going to use it (would depend on the answers to the above questions), I would not rinse it.

It was covered and I don't think any chemicals or pesticides got into it but you never know.
