very useful - thanks! have had a wildlife pond for years and no problems but have developed excess algae this year. After watching this I had a thought and followed the dog outside. He is weeing and it is running into the pond causing nitrate levels to increase. I have moved him away and also put in some barley straw. Hope the frogs appreciate it!

That's a really good tip, but how does one get rid of Duckweed (you know the little green single 'leaf' stuff)? I have oxygenators and a filter/oxygen pump feeding a little fountain, but can't seem to clear the duckweed short of spending hours with a seive!
