I'll offer a somewhat dissenting experience/opinion. I used GH three-part and had lockoutlike symptoms at 170ppm indicated. Once I went to RO, things improved. cn
...yeah man, I've seen alot of debates over on Al B Fuct's thread about using tap....Al says use it, I use mine...but some swear they have hella problems with their tap. I'm one of the lucky ones I guess that gets to use the public tap...I've used RO also, and I didn't notice a difference in my room...after the filters were old and rusty lookin inside my stealth big boy RO, I just put it away...now it's all tap, even for my flushing.
