Hi Dave I use Tri glaze conservatory roof sheeting just rest on top of the pond walls 7ft x 12ft surface area. These do fine I do pull one back through the daytime and slide back at night the sheets are about 6-8 inch from the water level but I do have a pitched roof on my pergola so laying them flat is ok as rain & snow seldom get to them.
