Installing a 12-24" liner of high plasticity clay in 6" lifts is the best way to seal a pond, but it's also often cost prohibitive. Polymer is environmentally safe and in my experience does not impact wildlife [amphibians] or fish negatively. I've seen a few FHM dead following a polymer treatment in a windblown corner of a pond that had the polymer coat the gills and suffocate, but that's been my only personal experience of a kill event. I've never seen any impact to aquatic vegetation - I like to treat ponds when vegetation is dormant. Feel free to reach out anytime, happy to discuss clay liner install or polymer and help in any manner possible.
