Could this sand be safe?

[Hholly]

So I bought a tank off of Craigslist that had been used briefly as a reptile tank. It had sand already in it that seems pretty clean. However, some of the sand is a reddish color. The guy told me he thinks it was called Reptisafe or something. Is it possible it would work for fish? I'm going to google around, but I just wondered if anyone here knew anything about it.
Thanks!

I wouldn't use it. It could have reptile waste in it. I would ditch it and start fresh.

There didn't seem to be any turds or anything dirty in it. No smell at all. I think it is this:

If it is pure quartz sand it is fine to use. I have some in my 10g tank. If it has come into contact with and reptile, even just a short while, I would use it IMO.

Ok thanks. The tank also came with a single bulb light fixture with a ReptiSun bulb. Would that be any good for fish and a planted tank?

It sounds like either a heat lamp or UV bulb. Idk if it will support plants. You can buy a new bulb you know will work for a few dollars so I'd replace it.
