Re: kH, gH, and Discus




: My question is this, does raising the kH also raise the gH, and what is an
: acceptible gH for Discus.

   KH and GH are seperate.  Discus can take about as much as you can throw
at them--water hardness isn't critical.

: Also, I'm using Sera kH-plus which causes the pH
: to go out the roof. Is that a common reaction when the kH is bumped up in
: really soft water.

   Yes.   Calcium bicarbonate (what KH measures) buffers in the alkaline
range, so raising the KH raises the pH.
