I setup a new tank, treated the water, dropped ph to about 7.1 or so, and
then let it sit for a few days. I put some honrwort in the tank, and within
24 hours most of the needles had fallen off. Temp is about 76-78. I've grown
hornwort in a similar tank before, and it grew like crazy. Any ideas what
caused this bunch to die so quickly?
