How do I change the water in my fish tank without killing the fish?

A 25% change is a good partial water change. Check temperature, dechlorinate and pour slowly back into the tank, and you should have no problems. If there is an emergency like high ammonia and nitrite, change 50% on a daily basis until those levels have come back down.

How long after changing the water can I add fish?
