How often should you test your aquarium water?
Test the pH, nitrite and nitrate in your aquarium at least every 2 weeks. zooplus even recommends every week.
Without measuring, you often only notice abnormal values when your fish are already ill. Weekly is the source’s advice; every two weeks is a practical estimate for an aquarium that has been running stably for a long time. Write down your values so you can spot trends.
- Take a water sample following the test kit instructions
- Test pH, nitrite and nitrate (and KH/GH if relevant)
- Write down the values so you can follow trends
- Take action (water change, feed less) if values are off
