If you put a KDF 85 prefilter in the RO unit it will remove all the chloramine for sure.What’s the EC of that waterYou sure your pH meter is accurate
I would calibrate it just to be sure
Also Get a RO filter that will help. Does anyone know if RO filters remove chloramine![]()
I've been using 1.5ml/gal House and Garden Reverse Osmosis pH Stabilzer to add a slight buffer of around 0.1 EC back to the RO water. That way the pH doesn't drop to 4 when I add nutes.
