Bio-Spira and Water Change/New Fish

[ScottyD36]

I was reading on the bio Spira bottle it says it can be used after every water change or introduction of new fish I want to see how many people actually use this when changing their water and when adding new fish. I always thought it was used for initial set up.

I think it’s great when setting up a tank or when setting up a quarantine system. Other than that, I never use it.
