Even through the last couple of months of January and February, the pond is green and I can't see what it going on. There are a couple of dozen frogs in there spawning at the moment. I have tried taking a lot of the lily pad out last year and using a silt product, but it is still so bad. I don't know how to get it back. I would really like to be able to see into the pond at the wildlife - if there is any - apart from the frogs!
