Our retention pond in our neighborhood has a lot of algae and problematic plant growth due to the surrounding farms and lawn runoff, so we're experimenting with a floating island to pull nutrients out before they can cause problems. This will also provide some interesting flowering plants, and more fish habitats.

Will be an interesting experiment to see what survives and what does poorly.

Zinnias, sunflowers, marigolds, and a few others are in net pots, inserted into cutouts in EVA foam mats.

Love it, but we're not as concerned about metals or toxins as we are about excess nutrients.

The papers I listed have plants that they've been using for their remediation, and we're following those lists. I know some of the researchers on those projects, and we'll modify our plant list based on any changes in their recommendations.
