Barley straw, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals
Copper-based algaecides use copper to treat algae growth, and are most effective against mustard and green types of algae.
Normally algaecide, like pesticide, is only a preventive and should be used throughout the pool season. But there are some algaecides that contain b14 or metals, such as copper or silver, which can kill algae. These algaecides may have to be added in large doses depending on the brand, but mixed with shock, can do the trick just as effectively as just plain shock.
Phosphates are food for algae, phosphates are in the runoff water from landscaped areas, some are by-products from what you add to your pool. This is food for algae and should be monitored quarterly and reduced or eliminated on a regular basis. The laundry soap you use for washing clothes and bathing suits contains trace amounts of phosphates, it all adds up to promote algae blooms. Test and eliminate on a regular basis.
The use of UltraViolet or Ozone will help prevent the growth of algae from the spores it produces. UltraViolet destroys the DNA and RNA chains of the algae and it dies unable to reproduce, Ozone will oxidize the spores and kill them on contact. I prefer UV over Ozone because it is much easier to maintain in the long run.
