Eggs or something else?

Tank is about 8 weeks old. Used fish fuel and Dr. Tim’s to cycle. Used caribsea aragonite sand and dry rock and rinsed before adding bacteria. I added two Clowns and a cleaner shrimp 4 weeks ago and added a clean up crew of snails and hermits last week.

Looks like Neritie snail eggs. They seem to like plastic. I have tons on the overflow.
