Can I use tap water for my fish tank?
Tap water should NOT be used in your fish tank because it contains chlorine and other elements that can be harmful to the fish. You can use dechlorinated tap water or purchase an aquarium-specific water conditioner.
This will aid in removing chlorine, chloramine, and heavy metals from the water, making it suitable for your fish. You should also test the water regularly to ensure that its parameters are within a healthy range for your aquatic inhabitants.
