Green Water Algae Control

 

As the days gradually grow warmer, plankton algae blooms begin to plague many ponds.  This is the dreaded "green water" algae that makes your pond look like pea soup.  

Controlling the causes of plankton algae is similar to controlling string algae.  It is simple in theory - just reduce the two things it needs to grow: sunlight and nutrients.  Last week's article provided some great tips on reducing these primary causes of algae.   

While these tips may work for many ponds, for others it is simply impractical to make much of an improvement in water clarity.  In these cases, an effective UV clarifier will work wonders.

 UV Clarification 

Ultraviolet clarifiers are a very effective method of eliminating plankton algae.  They are easy to install and do not change your water's chemistry as water treatments will.  When the clarifier is properly sized to your pond, your "pea soup" will turn into clear water within a week, many times in just a few days.  A larger benefit of UV is that it controls bacteria and parasites reducing the spread of fish disease.  

 This device is plumbed inline between the pond pump and pond filter. As the pond water is pumped through the ultraviolet clarifier, the algae cells in the water are altered so that they stick together and cannot reproduce. The algae cells are then removed by the pond filter or sink to the pond bottom where bacteria consume them.
