Had lots of watermeal and now.....*** What happens when it turns water grey/white film?
Watermeal needs a higher dose of sonar/whitecap than duckweed. More like 90 parts/billion. Mine went away on my 2nd annual application of duckweed-strength sonar, around 40-50 ppb.
translated: my pond is 1/3 acre and I only use 8 oz per year. (which I think is enough to treat 1/4 acre but I err on the side of caution).
