That's a large body of water for manual removal. Would take the entire community. To me there is a size cutoff on quick fixes or certain treatment. You almost can't tint a lake that big. You are 100% correct that it is better to remove the stuff than load your pond with copper, kill it and feed the next bloom with dead algae. Also the O2 depletion. Where grass carp will not eat it, Common Carp will. We use a lot of hybrids with great success. They don't reproduce very well, if at all, and they just eat that algae up. It is almost first on thier list. Negatives are you are stuck with a ton of carp, which can be turned into a positive with community carp hunts, and fishing tourneys. And they do roil in the mud and make the water turbid/cloudy. Especially where they feed. We have many drinking water lakes, where they are thick, and there is zero algae. I have a big pond that cycles through, the water temps increased, and it is almost gone now. The bigger the body of water, the more expensive and tougher the solution. And the expense skyrockets.
