Tap Water for House Plants – Dechlorination

Q: I have several fish tanks and use a de-chlorinating product when using tap water for water changes. Would it be beneficial to use such a product when using tap water on my house plants?

A: I don’t think there would be a benefit. Chemical dechlorination typically yields a tiny bit of salt, which plants don’t like. If you are worried, use distilled water or rainwater.
