I was with Nathan at the convention this year when he spoke to George Batten, Seachem's research chemist, about this very topic. I believe George said that equilibrium is not for *completely* reconstituting RO water, and that they were still working on a product to do this. My understanding from the conversation was that equilibrium is a supplement for softer water, but can do some squirrelly things if used by itself.
I've had absolutely no success with Equilibrium, RO Right, or your GH Builder when used to reconstitute RO. Hence my interest in simply diluting the tapwater. And then letting whichever plant that grows best in the result take over the tank.
PS: Sorry about dragging stuff from APC over to here, but it's relevant and I wanted your opinion.
