Hard water

  1. Hey everyone, I recently got a TDS meter and I found out that my regular tap water has a TDS reading of 550ppm. I heard that if your tap water was more than around 200ppm then you have hard water. So is this bad or what, my plants look alright.
  2. its not bad but its not good. theres a lot of salts in your water then. you should just flush your plants more often to help with salt build up
  3. oh ok thats a good thing then. thanks
