While tap water might seem like an easy solution for your Goldfish tank, it’s not advisable to introduce Goldfish directly into untreated tap water. This is primarily because tap water often contains chlorine or chloramine, which can be harmful to your finned friends.
Before adding tap water to your fish tank, it’s imperative to use a water dechlorinator to remove these harmful chemicals. Additionally, matching the water temperature with existing tank water is crucial to avert thermal stress when adding new fish to your established tank.
