Can I use tap water for my fish?

Generally, you need to take a few fairly simple measures to make your tap water safe for your fish before you add it to their tank or pond.

This is because:

  • The temperature of the tap water is likely to be quite different from the temperature in your tank or pond
  • Tap water may contain traces of metals that are harmless to us but can damage your fish
  • Tap water contains a small amount of chlorine to safeguard our health, which can be harmful to your fish
  • The acidity of the tap water is likely to be different than the water in your tank or pond

Check with a local pet store to determine if you need to dechlorinate your water or for other precautions you may need based on your household plumbing and variety of fish.
