Working on a duckweed killing formula and figured I'd keep a log on here. (thought about you andy :evil_lol
It should be relatively fish safe, but time will tell..
Anyway, still tweaking and adjusting things, but here goes. (far right container didn't get labeled on the first pic but it is regular strength)
Each day the containers were each sprayed with the according dose of duckweed killer, approximately 2ml give or take.
Both of the treated containers appear to be dying and concentration level doesn't seem to affect that in any major way, so that's a plus because dilution is always a good thing.
I'll start my next test in a few days and dilute it to half/quarter strength.
Any comments?
