P.C- QUOTE = I switched from R/O to tap water recently and I'm still adding Calmag+ to my solution. I don't know if I need it or not, but I'm only using 1ml/gal so it's just kinda cheap insurance as far as I'm concerned.

Hell yes P.C - It's much easier to avoid a def. all together - verses trying to diag. / fix 1 . :thumbsup:

I didn't add in the base ppm of my tapwater either before I got my r/o system . But I do disagree about the additives coment . What if the additive is Koolbloom = a blast of phos. It ups my ppm by 200 or better . Do you use any boosters etc... ?

Peace
