Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Better to broadcast or spray Copper Sulfate?

Thanks for the tips guys. So from what I read, Copper Sulfate is by far the least expensive of all algae treatments and I bought several 50lb bags before I researched a lot. From what I've read, Copper Sulfate breaks down the algae and produces sulfate in that process which can feed additional algae. Not ideal. I have no desired fish yet, so that's not a problem. What else do you suggest I use instead of copper sulfate then? The lake is currently only about a 3rd full.

Note, I plan at some point in the future to add lake aerators, but that will be a few years out as I'm unable to afford that at the time. I would like to stay ahead of any growth problems by keeping it clean. Your suggestions are appreciated!
