thanks for the update I am seriously following this. How is the price compared to CPE?
my only question is this, the absorbtive (is that even a word?) properties of g.a.c. become diminished much faster in an aquarium than g.f.o. from what i understand, so are you gonna remove g.f.o. that still has some use left in it, or keep depleted g.a.c. in your system? i thought that that was the reasoning behind dual reactors.
any update?
any further update on this???
Matt, are you sure it's not just a "false reading" and that the HA isn't just consuming it all?
