Hi
I hope someone can give me a pointer or two on curing the green water in our
pond. Appeared a few weeks back - we live in South West UK so it is just
coming into spring. I have tried several products to clear it without
success. I have tested the water for nitrates, nitrites , ammonia, PH etc.
Apart from a slightly alkaline PH reading everything is pretty much normal
but the green water will not shift so any suggestions much appreciated

thanks in advance

Jon
