When I had a small pond, I often got frog and/or salamander egg sacs. I just let them be. They usually hatched out to pollywogs and through natural attrition (birds, perhaps the goldfish, small mammals, my cats...) I never had any issue with too many growing all the way to frogs. Some likely did, then hopped away. I still get tons of 'peepers' in my pondless water feature and assume there may be egg sacs in the water reservoir that I just can't see. Let nature take its course is my advice.
