Hey guys

Question for all the pros out there. What's the maximum ppm for your tap water before you reckon you filter or go buy RO? Obviously this will be influenced by hard or soft areas and the growing  medium. I have a hard water with a ppm of 160 odd. Growing in Coco. Bit concerned about limescale buildup over time but it does offset adding calmag etc to RO. Thoughts?
