This might just be my irrational fear, but whenever I do a water change, I'm always concerned about something getting into the water that might contaminate it, whether it's a household soap, shampoo (I prep everything in the bathtub), or something else. I end up obsessively rinsing everything to try and avoid it, which makes water changes such a dreadful process.
How intensely do you try to mitigate against any contamination of aquarium water? Do you take any measures during water changes?
