Thanks for the contact info. I deal regularly with a company (Altium) which was based in Australia before it moved to China so I usually call first thing in the morning, around 7AM which is the end of a late day for them.
I may have some work to do raking out some chara and removing two Christmas trees on my dam side in prep for application, making a mess of the water quality for a bit, but if it works, it will be worth the effort. I noticed all videos showed application to relatively new water basins, or ones recently cleaned out. None appeared to have vegetation apart from some grass.
