About the only way to keep frogs out of the
pond is to net it securely. Removing the eggs
when they get to be too much is a good compromise
(just take them to a natural waterway).

I agree with George. Check your water tests, especially
ammonia with all the frog activity.

Usually algae that floats up to the surface means too
much organic matter in the pond. And could be a sign
of blue green algae which will make fish sick also.
You may need to reduce your stocking level (here
Mother Nature may be doing it for you).

Barely straw.... don't use it as I don't like the idea of
any more rotting organic matter in the pond than what
comes naturally. But others do so maybe they can answer
your question.

Sound likes like you are really enjoying your pond and
with some adjustments you probably will be okay.
