Has anyone had any experience using it? I have a 15ftx12ftx3ft pond, no fish, no floating plants, the sole function is reflection and movement. It gets some blanket weed, and you can see the bottom where leaves and sediment collect. Maybe a dye will prevent the algae, hide the unsightly base and enhance the reflections?
I can confirm that this works well, the colour of the grey product is natural. It stops you seeing the bottom of the pond with its unsightly leaves and it reduces algae growth dramatically.
