Getting rid of green water with willow method

     Green water appear usually due to either a significant excess of light (particularly direct sunlight), or a major water quality problem. Although it may look terrible, it is not toxic to fish. The best way to get rid of it is by using an UV, but if you don't have one, you can use the willow method.

     Step 1: Pluck a few branches from the willow trees.

     Step 3: Put the branches into the tank with the part without leaves soaking inside the water, about 30 branches at 80 liters of water.

     Step 4: Wait patiently for few days and you will see roots starting to appear from the branches.

     Step 5: The Green water should be completely gotten rid off after a week and this effect usually come overnight!

     Step 6: At this point of time remove all the willow branches else your plants will suffer from the lack of nutrients.
