Re: RO Water Additives?

Everyone - Thank you very much for this info!  I guess I never thought to 
ask - silly me.  Kevin - I'm from Waukesha, WI and I use RO/DIO water in all 
of my tanks - it's nice to see someone from this area.

I don't mix with Tap because of the hardness and PH.  I have been struggling 
a little with a combination of additives in order to keep my water soft and 
PH low.  The recomendation below may save me from some of this headache!  
Again, thanks!
