You generally want to wait at least two weeks between introducing new additions to your fish tank. This gives time for the biological filter to get caught up again.

How do I know when my aquarium is ready for fish?

Can I add water conditioner while the fish are in the tank?

Does letting tap water sit remove chlorine?

When chlorinated tap water is allowed to stand around, some of the chlorine gas will indeed escape from the water’s surface, whereupon both the chlorine odor and the amount of HOCl in the water will diminish. That’s because as some of the chlorine departs, the HOCl in the water produces more of it.
