Re: RO against Seradest (+ anybody from Belgium ?)

Well, this seems like a good time to test *my* connection...

Two questions:

1. How quickly are these concentration shifts taking place? I realize this
is most likely _not_ the case, but your posting leaves the impression that
it's rather quick.

2. What's happening in your tank as far as _alkalinity and pH_ ? Again, your
letter implies that your focus seems more on hardness. If you're making
40-50% reductions in general hardness you're also affecting the KH,
obviously, but its effects aren't quite as linear as hardness. Plus, peat
filtration is considerably more active against KH than GH, so there could be
a lot more going on than simply softening the water...
