It will depend on your tank system and how quickly it mixes your tank water. I have taken tests in my system about an hour after adding my supplements and then re-tested 24 hrs later and found the results the same. ;)

In my 29g tanks, 10 seconds was plenty of time. For systems with a sump, it might take longer.
