I am new to all this also, so don't take anything I say as fact...LOL
Yes, I was told when I apply the fluridone to just mix in with pond water in a 5 gallon bucket and pour in several areas around pond by boat if possible, near aerator being best...
The pond I just sprayed was a half acre...I applied with a 2 gallon hand held sprayer...Took about 2 hours by the time I dinked around and cleaned up...
There are many guys here that do this for a living that will chime in and give you the ins and outs of how this stuff works..I just try my best to be a good student and share what I have learned...
