troutrus,

Hopefully you are close to peak algal bloom.

I know that the massive bloom is a little disturbing to observe in your beautiful pond.

The good news is that the very bottom of your food chain is getting the best "crop" it has ever had. All of the organisms that consume algae should be eating their fill.

That level of organisms then feeds your LMB and BG fry shortly after they hatch.

I would recommend you keep an eye on your aeration. If there is an algal crash in your pond, the decaying algae will CONSUME your dissolved oxygen. Need to keep your aeration going through that period - just in case.

I suspect you will start seeing natural improvement within two weeks?

Can you discourage the ducks next year, or were they family favorites? Most people on the forum manage their ponds primarily for fish - but there are lots of people on the forum that manage their ponds for a diverse array of wildlife.

Some people with large ponds even put up nesting structures for wood ducks. However, your three ducks were probably a little too much for your pond.
