Re: Altering Water

[Steve Lasky <festae00@yahoo.com>]

It's late so my memory could be malfunctioning worse than usual but.. an RO unit
will lower the pH a little.  However, the reason I want it is for what Kevin
said.  It removes the impurities in the water (DI does so even more, hence why i
want an RO/DI unit) which add to the hardness.  Remove the hardness you remove
the buffer.  Once the hardness is down low, pH manipulation becomes relatively
easy.  At that point, it's a simple matter of playing around with different
ratios of tap to ro till the right balance is achieved.  By balance, I mean pH
and hardness.  Hopefully i'm somewhat right :)
