This is the most FA we've ever had by far. My bride and I are working on getting the mats removed and will follow up with a copper sulfate treatment. I think I've read here that Alum might help. Anybody have any experience with using Alum to fight FA?


Just to follow up on this...I applied the copper sulfate to fight the FA. Due to recent surgery, my application options were limited. I went with 1 pound of CS per gallon of hot water in a pump sprayer. 7 pounds of CS total in our .5 to .6 acre puddle. I am hooked! Absolutely incredible results. After a week or so, we were FA free! We are starting to see some signs the FA is trying to come back, so I will hit it with a lighter dose. I'm thinking it will be a monthly activity thru the summer. I used hot water to make the CS dissolve easier as well as helping the mixture disperse more in the cooler pond water.
