Don't see a lot of red algae out here, in fact, close to never. Just on the coast. Makes sense as the 2,4-D is all but gone by now. So when all of the dead milfoil sank, it opened up all of the water for algae bloom, looks to be two different kinds. It also reloaded the pond with even more nutrients. I might have treated 1/2 to 1/3, and as soon as it started browning rake it or push it to shore. Tomorrow I have a 100% coontail infestation job. No chemicals, just mow with Jenson Lake Mower and rake out. Going to mow down to 7 foot mark with extender. Customer had a bad fish die off when dead material sank and rest of live sucked up remaining dissolved O2, a mini crash. Goign to be about a 2 year process to fix that. I figure we get 1/2 acre tomorrow.
Now you have a few things to deal with. Provide some type of aeration to speed up decomposition of milfoil you cannot rake. Or don't want to. Helps the bacteria speed along as they need that O2. Bad part is you traded one situation for another, not as bad, and have a lot of nutrients that are not being handled the way you like, and that may or may not work itself out. In some of my ponds I've had algae all season this year, not normal. I do think it is a bit easier to treat algae than milfoil. Not uncommon to do a chemical treatment, open up the water and have a large algae bloom. you just don't know if that will go away or is there to stay.
