Ultraviolet Sterilizer Tetra GreenFree UV Clarifiers

 
 

TetraPond® dependable UV clarifiers use ultraviolet light to destroy the reproductive activity of suspended single-cell algae, resulting in clear, green-free water.

Dead algae then clump together into particles large enough to be removed by filtration, leaving the pond cleaner and clearer. GreenFree Clarifiers usually remove heavy algae blooms within eight days and keep water clear and green-free.

How to get rid of green water?

Algae in the form of "Green Water" commonly occurs in ponds. The algae itself is not a problem but it looks unsightly and hides your fish.

Fortunately there are a number of things you can do to rid yourself of green water. Algae requires nutrients and sunlight to thrive - so therefore the goal of the pond keeper is deny algae these ingredients.

  • Shade as much of the water as possible with lilies and other aquatic plants. Algae requires sunlight - so floating plants prevent sunlight from feeding the algae.
  • All aquatic plants absorb nutrients from the water that would otherwise be used for algae.
  • Feed your plants only as directed. Fertilizer tablets can be inserted into the soil - so the fertilizer is absorbed by the plant roots with very little released into the water for algae to consume.
  • Aqua-Zyme
  • AquaRem
  • A guaranteed way to keep water clear is the addition of a UV Clarifier.  Exposure to the correct wavelengths of UV light kill the DNA in algae. Once it dies and clumps together, the external filter can filter it out. This has become a very popular and effective way dealing with green water.
