Hard water and ina humidifier

0-20ppm of what? I've only ever tested the ph of my tap water and I thought it was bad coming in between 6-7 ph.

Parts per million. Get an ec meter they're cheap on Amazon or hardware store. Probably just abit or residual stuff that made it through the filter. An ec meter really helps to see what you have in your water before you put in your nutrients in and afterwards just to have a good idea of what you're actually putting in. Some feeding schedules say how much you should put in and it's measured in ppm as well as tea spoons or millimeters. I have 2 EC meters. One for usual use then one to make sure it's still working properly, same with my ph meter I still use the strips from time to time to check if my meter is reading properly.

Good to know thank you so much. I'm going to amazon right now to grab an EC meter.

From what I've noticed ordering different brands. It's the same meter with a different name on it or different colors lol. But they all seem to do the job. Read the same.
