Silly me. I think what I scooped up was actually Koi semen. 30

Exactly right! Spawning is one of the primary causes of foam in a garden
pond. It _is_ a good idea to scoop out the foam.

Because my ponds are netted that would be a real pain in the keester. It
disappears in 24 hours on it's own. The first time they spawned several
years ago I checked for an ammonia spike - there was none.

It's not a hard rule - and the bigger your pond the less likely it is to
cause trouble. If ammonia never appeared, it's not a problem at all. But
foam of any kind indicates a high organic load in the pond, and scooping it
as it develops is the simplest form of control. If it was a real problem,
then you'd want to consider a protein skimmer - which wouldn't be a problem
with a netted pond.
