My 500 liter garden pond had grass green water in which one already in 15 cm depth could not see the hand. My first attempts to master the algae I made with the lactic acid bacteria contained in Brottrunk. The pond was slightly clearer and the goldfish in the spring much more agile. Easily clear means by no means that I could see the bottom. In the first application of Algo happened almost nothing, even after weeks. To be as the water started again after a cleaning and changing the water green I went on to plan B. A mixture of Aqua Activ algo and PondClear brought a surprise, I saw for the first time in 60 cm depth the bottom of the pond. But you should also be aware a turbidity of the water also produces a pump in the pond and the chemicals do not promote the growth of other pond plants.
