Hi
I usually am a google reader and find info on the net. But this one I'm truly stuck with.
TDS pens. Used to measure total dissolved solids/organics etc. my question is what benefit is it when using RO or distilled water. The organic or "dissolved solids" would of been removed so leaving it in a more clean natural state. All those harsh chemicals are removed.
So if I dose macro/micro's would it be any benefit to me in helping keep my water clean, healthy and full of nutrients.
I do test all the standard tests + phosphate iron GH/KH
Thanks
