I agree with esshup. It appears the bloom material is floating. It is probably good to trim the bloom by treating part of it each time. Be aware when killing part of it and it dies and sinks it does not remove any of the nutrients that caused it to grow. Recycled nutrients from algae decay will eventually be redissolved into the water column to feed the next bloom. To reduce nutrients I would be creative or imaginative and figure out a way to remove or suck out the surface film. This removes the source of the problem and the surface film problem plus there will be no dissolved oxygen sag when the dead algae decomposes. A win, win, win to the pond ecosystem. .
