Tetra Pond UV Sterilizers
Green water got you down? Is your pond starting to
look more like a swamp than a water garden? Well worry
no longer - in case you haven't heard of or used a UV
sterilizer before, the good news is that they work, and they
work very well..
UV sterilizers work by passing your pond water through a
chamber containing an ultraviolet lamp inside. As the
water passes through - the UV lamp damages the DNA of the
suspended algae cells, and prevents it from replicating,
which means no more algae.
This month, we are going to highlight one of our best
selling UV sterilizers, made by Tetra Pond. The Tetra
Pond UV sterilizers are extremely economical, easy to
install, and very effective. They are really more of a
'clarifier' than a true UV sterilizer, but the end result is
the same - clear water. True UV sterilizers typically
use a higher intensity bulb, and longer contact time.
These units will also help control parasites and bacteria in
the pond, but can be very expensive and are best used on
larger KOI ponds.
But for the average pond and water garden owner, with
ponds as small as 50 gallons, all the way up to several
thousand gallons, Tetra makes a suitable UV unit to meet
your needs. For more information on sizes and pricing, please click
Here are some of the other benefits of this unit:
Here is a diagram showing how the unit works:
In the past, pond owners were only left with a few options
for controlling green water. The most common was to
pack as many nutrient absorbing plants in the pond as
possible - hoping that they would essentially starve out the
algae. This method was / is effective on smaller ponds
mostly, but not cost effective for larger ponds due to the
amount of plants needed.
Another drawback to this method is that in most parts of
the country, cold winters will cause these submerged and
floating plants to die off. Then you have to buy them
again in the spring time, every year.
So in the long run, it is more economical to just invest
once in a properly sized UV sterilizer. We've used the
Tetra units for years, and they always work well.
Typically, a UV sterilizer will clear a green pond in 2-3
days, and keep it clear (depending on the filtration system)
As far as maintenance, there really is none. Just
plug it in, and connect it to your pump, and that's it!
Bulbs usually last 12 months of use, or one full season at
least, and are reasonably priced for replacement bulbs.
If you're not as happy with your pond water clarity, and
especially if your pond is in full sun with few plants, then
you should really consider adding a UV sterilizer to your
In our opinion, no pond should be without
