Every spring my 1/2 acre pond has a boom of FA. I do have 2 bottom diffusers for aeration and they do a great job keeping the pond healthy. Its normally just the initial snow melt and run off of from the fields that makes for a back breaking day of trying to rake it all out. I have used these(see below) before and would say they did a good job, but they are very expensive, especially if you had to get one every 30 days! Is there an alternative product I could buy you would suggest? And can I find it in NY, some places wont ship the chemicals here. Thanks. Below is the link to the product I mentioned.
