So I tested my tap water and it came in as 125ppm but they also treat it with chloramine, I tested distilled water to make sure my pen is accurate and distilled water showed 0 so safe to assume pen is accurate.. is my tap water safe to use for plants? ..usually I get distilled water at store but buying 20 jugs every 5 days gets annoying..any opinions would be appreciated
