Why did the CalMag help Loc Nar? Because that's what his Britta filter is stripping it from his water and leaving the sodium. The thing about RO or distilled.....it pullls EVERYTHING from your water....including the extra sodium our plants DONT need, We started out with a Britta filter as well before going to RO and it was a MESS. We use well water and had trouble holding ph. You apparently do not have the same issue!!! lucky you!!


What's the ppm of your tap without the filter? If it's 200 or under, lose the filter and add a couple mls/gal of Cal Mag. That would the very first thing I would try.

Good luck.

PS......looks Loc Nar beat me to it. I won't forget that loc nar.
