Can aged water get "to old"?

Can I fill and treat a 20 gallon tank and use it for water changes? Instead of preparing water everyday for the next day's change. Or would it get to old and lose its "goodness"?

Why cant you fill up the bucket on waterchange day? And I dont think it will lose it goodness

Water is going to be changed daily. Probably more often until I catch on to getting the dead brine shrimp out easy and they get bigger. Most things I've read say to change water at least once a day if not twice.

I'm going to be keeping them in my bedroom because it's the coolest room in the house and I'd need a looong hose to run water in there.

I was also worried about a new plastic bucket (don't have any) leaching stuff into the water and thought using the extra tank would be safer.

I'll probably use the tank either way, just trying to decide how much water to do at a time, and it still stay healthy for them.
