I don't want to cover all the ponds as birds drink out of them all winter. Plus I won't be leaving these covers on past March as I believe direct sun essential in early spring. I did cover the ponds once many years ago but left cover on for too long and mold grew under water on all the edges of ponds and including a film of mold on fish. Once I took the cover off the mold was killed in a day or two by direct sunlight. Fish were all fine and mold disappeared.
