Old Water?

[Realm]

Hi
There's something I've been wondering about, how long will still, dechlorinated water last for before it becomes unsafe (if it does)? I have a tank I filled with dechlorinated water which was going to house a few creatures but I ended up never using it. A few weeks later however I did need to use it, and I decided to sanitize the tank and replace the water just to be on the safe side. Was this really necessary? The water didn't look or smell off.
Thanks.

If the water was unfiltered then I think that you did right by throwing it out. If it was filtered then there should be no problem.
