Green Water Treatment

Green water is caused by algae cells floating in the pond. If there is a lot of sunlight and your pond water is rich in nitrates algae will multiply rapidly. Green water is most effectively removed by using a UV Clarifier in conjunction with a filter, however sometimes you need to give things a boost by using an additional pond treatment. Algae are primitive plants that, via photosynthesis, combine water and carbon dioxide to form sugars for energy and growth. Algae produce oxygen, a useful by-product, but when sunlight is not available at night, they quickly respire. There are basically two types of pond algae:

Green Water: These single-celled organisms which remain suspended in water are so tiny, they pass through even the finest filter. If conditions are right, meaning there’s plenty of nutrients and sunlight, as many as five million algae cells per milliliter of pond water can be present. String Algae (also known as “hair algae”) this filamentous species, which grows in long strands, adheres to rocks and waterfalls. They eventually tangle together, forming thick, unsightly mats that can double their weight within 24 hours.

The following are some tried-and-true methods that will not only help you treat algae, but also help prevent it –Add plants ,Water Treatments, Fish Feeding, Green Water Control: Ultraviolet (UV) Clarifiers, String Algae Control: Garden Hose, Hand, or Net, Consider water dyes to help as they block direct UV rays coming from sun. By twirling it around a bamboo cane and hauling it out you can achieve some control and there are products that will help to get rid of it.
