so i guess for the lowermainland a reading of around 10 is the average. I was wondering with a TDS of 10 is it really necessary to run it through a RO/DI filter? I mean would 10 really do harm to a reef tank? Anyone around the lowermainland using tapwater for WC and topoff regularly without any issues?
