Today i found that my tap water is 500+ ppm. Is is ok to use bottled water with 191 ppm Ca 68,4 mg/l Mg 4,97 mg/l So 9,46 mg/l is sodium to much? And im useing general hydroponics micro hard water thanks in advance.
500 is not the end of the world ya filter or bottle water is better just make sure you PH it and to go one step more just leave the water out for a day or so and the PPM will drop to around 250 300 as it vents off all the crap in the water
