Has anyone tried it with vascular plants? UG n' such?
Philosophos;40679 said:What I haven't seen done is long-term treatment. Small doses, every day, like excel. I'm sure if we dumped in enough excel to get those sort of results, we'd be doing FAR more than normal.
As it happens I'm about to have an excess of hydrogen peroxide around in the next couple of weeks (don't ask)... maybe I should do some tests on a small scale.

If I understand your post(s) correctly... then low dose H2O2 does not have an anti-algae effect because there is not enough oxidation. And increasing the ORP doesn't improve plant health in general.
It means I've got more work to do to focus on plant health.
