ro water is not unstable, there is nothing in it. Taking the pH makes no sense.
when you add nutes you may need to let it settle for a day.
demoreal Reviewed by demoreal on . Tap vs Filtered Water I have general question between the waters. I know filtered water is just what I said filtered, but I still have to ph it down to get it right level. Cant I just do it the same with tap water or does tap water have to much other chemicals that can damage the babies. :jointsmile: Rating: 5
