Algae
Green unclean water is a frequent issue with more compact ponds. A small amount of algae exists in all water; having said that, in lengthier intervals of sunlight even an ideal equilibrium of fish and plants is just not sufficient for complete avoidance and the water can becomes a livid green color. In tiny still-water garden ponds this can be prevented with the setup of a purification unit such as UV sterilizers.
If you have fish or any aquatic life in your pond it is advised to not use the UV lights as these are designed to kill any and all bacteria - good and bad. The life forms in your pond need the good bacteria. So you an organic pond cleaner in this case.

Do NOt over feed your fish
Fish food that is not digested by the fish is the main pollutant in many ponds. Too much food for the fish increases waste and provides nutrients that feed the algae.
Plants in ponds
Plants in ponds will reduce the amount of algae that is able to grow, but also use the waste from the fish to give a natural water filtration system.
