So I have hard water and it's treated with salt, it is then passed through a carbon filter in my fridge, but after just 3 waterings I can already see a white build up on the surface of the soil, like I was told I would see, I was told that even with the carbon filter it would still have a negative impact on the plants. Is this true? What else can I do besides buy cooler water?
