I get a foamy surface after the frogs have spawned and the spawn is
decomposing. Could it be this?

Not the spawn, but the male addition to the deed, and/or pollen can cause
foaming, but we've had lots of pollen blowing around here and none on the
lily pond till the frogs got hot & heavy. Hopefully I won't find any
drowned in their passion like last year, one young couple fed the tomatoes.
