The reason garden ponds go green and/or murky is because microscopic algae is suspended in the pond water. These algae come to the water surface to absorb light necessary for photosynthesis. The fish in the pond don't mind the murkiness but the pond owner does.
There are in general two ways to get rid of this murkiness or pea soup water as it is often called.
1. The use of additives such as Viresco Aqua or Viresco Koi. More often than not this is a short term measure since the algae will return once the additive has been used up. Nevertheless it is an effective way and is initially a low cost approach and no equipment is necessary.
2. The installation of an Ultra Violet Light Clarifier (UVC) which kills the algae that is pumped through the UVC unit. This is a very effective way of controlling suspended algae and if sized correctly works 100% of the time.
