I have a 1200 gallon pond with koi in it. While cleaning the filter, my husband noticed about 10-12 round, clear "balls". They are about the size of a marble and firm but pliable. They are just outside the pond, so they are not wet. Could these be frog eggs?, and if so, will they survive out of the water? I'm afraid to put them in water, as the koi might eat them. Should we put them in a shallow container until they hatch?

Frog eggs are soft, jelly-like masses, and their yolks are dark. At least, that is true for the frog eggs that I hatched when I was a boy.
