Understand this about RO filtered water. it is as close to pure as you can basically get.Hound is right.RO water is the very best to use once you learn how to use it.Most people have never even tasted "pure" water before.Likewise, most plants haven't either.Your plants will love it.
Deejay2163 Reviewed by Deejay2163 on . New RO filter question I just hooked up my new RO system. The water tastes great, way better than the old tap water. I tested the pH of the RO water and it is at around 8.0 (jumps around a lot for some reason). I expected that the water would have a ph of 7.0 (neutral). What should the pH of RO water be? I know I should be checking the TDS of the water, but my TDS meter is in the mail. Would this water be safe to feed to my plants if I was to bring the pH down to 5.5-6.5? Rating: 5
