Duckweed elimination is one of those "says easy/does hard" type of things. It reproduces at an amazing rate. Thankfully, I've never had it. The only thing I've heard of working is nuking it every time it tries to get a start. After the first chemical application, you have to keep hitting it.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Without a sense of urgency, Nothing ever gets done.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP Grandpa
