I have recently installed a waterfall around my garden pond. I have
noticed
a build up of foam in a thin layer in the pond.

The foam is from protein caused at this time of year by the fish....or
frogs or
toads spawning. It will clear up when the spawn stops. Jerri

To add to the above. A filter may also help to breakdown this more quickly.
