Pond Boss Forums INTRO Questions & Observations Blue Green Algae in Oakwood, TX

A few weeks ago, chunks started appearing on my pond, quarter to half-dollar size, not a continuous sheet. Over time there got to be more and more of them and when the wind blows they pile up. Some drone footage from yesterday shows that at present there is more of a sheet with the chunks embedded in it than it would appear from ground level. The pond is 5 years old and I've never seen any of this before. Makes me wonder what is different now. This summer has been incredibly hot for the longest stretch is the only thing I can think of. We've had plenty of rain to keep the pond topped. We had 5.2" of rain the other day which drove it all down but it just all popped back up again after a couple of days.

What do most people actually do about blue green algae? I would guess nothing, and hope for the best? Some of the solutions don't sound too appealing if there's a possibility that it is eventually going to resolve itself, maybe with fall just around the corner? Is the stuff on the surface actually dead already, with living algae down deeper? I know the stuff can be toxic but has anybody on the forum actually had a fish kill from a blue green algae event? I see little fish swimming right amongst the stuff to seemly no ill effect.
