Our Ohio Pond was built in 1999. It was an incredible fishery, until last year when duckweed was introduced somehow. Duckweed sheeted the surface quickly. I asked various people for advice and tried netting, raking, etc. We ended up waiting for the cold weather to take it out. Unfortunately, it killed most of our big fish last year before the surface cleared for winter. Then, it came back this year in a hurry when the weather warmed up. We had aeration last year, but added more. That was not the answer we were looking for. Duckweed still grew thick over the pond surface. Duckweed is terrible for a fertile pond owner. It will starve your fish to death by blocking the Sun light and disrupting the food chain. It shades and kills good oxygen generating plants by eliminating them temporarily. Our pond has seasonal springs, so as soon as the drought hit and the water stopped flowing out of the pond outflow pipe, we added Spiritflo. We noticed right away that duckweed stopped expanding , then, died slowly over about 4.5 weeks. Don’t waste your time! I bought a weed net and some other things people recommended. As a very fit individual, I could not keep up with duckweed growth. What you take today, returns tomorrow. Spiritflo is a duckweed eliminator! It seems to be slowly killing cat tails as well. Curly leaf is another very annoying plant at times that seemed to perish with Spiritflo. In 4 to 5 weeks, we got our pond back. Also, we added some tilapia from a local hatchery. They are a seasonal fish in cold states. Additionally, we used enzymes/bacteria to take care of the dying plants. The pond water is now clear as an aquarium and weeds seem to be disappearing completely. There is still floating algae at the one end of the pond. We re ok with that, as it appears to be a normal. I wish, we knew about Floridone last year. We are glad to have our pond back. Fish were restocked and seem to be doing great again. If you get duckweed in a good fishing pond, call this company and speak with their staff right away. Floridone was our answer. I spoke with a female at this company and she assured me this would work. She was right. I hope this helps you keep your pond functional and looking awesome.

Saw results in only a few days and after 2 weeks, almost all the duckweed is gone.

My one acre pond was covered in duckweed and I used Fluridone to treat it. The duck weed is now gone and my pond looks fabulous! Thanks Lake Restoration!
