I do not think that leaves are the culprit. I have a large Levy over half of the pond has no trees and because of the spillway most of the floating leaves make it to the spillway and go down the creek before sinking. I'm thinking my fish population is too high and I'm not harvesting enough? I do have test strips and everything seems to be in the normal range. The aerators are definitely helping with water clarity but obviously appear to not be doing anything to fight the algae. I'll take a video and post a link later today thank you guys

Test strips can't monitor the level of nutrients in the pond. They can't test a small enough amount. Leaves DO contribute, even though you don't think so. So does dust, pollen, basically ANYTHING that goes into the pond adds to the nutrient level.

Anyplace that sunlight can get to the bottom of the pond algae will grow. In a shallow pond, that is pretty much everywhere. Tilapia will help next year. Feed less, harvest more will help, planting underwater vascular plants will help too. Sourcing them is the issue.
