Hi! I live in NW Ohio where a majority of the ponds are 1/3a to 1/2a. They are primarily used for drinking water and recreational use. Most want a VERY clean looking pond. So while I can help them kill/control the unwanted algae, they want it GONE. Can anyone give me an general idea of how long it takes for chara to totally decompose? I understand there are multiple factors that come in to play. I'm just looking for a general idea. 1 month...1year? Thanks for any help!
