Do UV pond filters work?
Technically, a ‘uv filter’ is not a filter, because it doesn’t physically remove the dead clumps from the pond. It only kills the free floating algae, and is usually called a ‘clarifier’ or a ‘sterilizer’. You still need a filter along with it. So from now off on in this article, we’ll be referring to these UV pond filters as “UV pond lights”.

Can you have too much UV in a pond?
You can't have too much UV in a pond because the UV device only affects algae cells that go through the unit. So plants and anything else not suspended in the water are not harmed. However, it's possible to have a device that's too small for the job but you can't have too much UV.
Do pond UV filters work?
By definition, UV systems do not function as filters. That's because they don't actually remove any unwanted material. UV clarifiers, as they are better understood, function as sterilisers because they work simply by killing algae. however, the algae still remain in the water because UV Clarifiers do not remove them.
Where do you put UV light in a pond?
When it comes to installation, place the UV clarifier where it won't be flooded. It is waterproof, but should never be submerged in water. We suggest mounting it onto a dry flat surface, like the lid of the canister pond filter. And always connect the UV unit to a GFI outlet or circuit to protect against shock.

What happens when you put a UV filter on a pond?
When water is pumped from your pond through the UV filter, the single-celled algae are exposed to very high levels of ultra violet light. This destroys their DNA and causes the algae to divide. And when they divide, they die, resulting in them clumping together. These clumps of dead algae can then be removed from the water.
Where do you put UV light in a pond?
Where do you place the UV light? The obvious: The uv light is placed inline with the pump and the filter (either a mechanical or biological filter). The pump gets the pond water to the uv clarifier/sterilizer, and the filter takes care of/removes the dead algae.
What happens when water becomes less green?
When the water becomes less green, there will be less algae to clear out and thus the filter will remain a lot cleaner. You can also use a biological filter. Instead of physically removing the dead algae and other biomatter from the water, these are trapped in a tank that contains beneficial bacteria.
How to get dead matter out of pond?
There are two options: The simplest: you can use a mechanical filter to get the dead matter out. Well, rather, YOU get the stuff out by backwashing and cleaning the filter .

Why do biological filters have UV light?
There are a couple of good reasons for this: The uv light works more efficiently when the water flowing along it is clearer.
Why do UV filters have a max flow rate?
The slower the flow, the better. If the water flows by too quickly the uv light doesn’t have a chance irradiate all the algae. The slower it goes the more efficient the process. That’s why these uv light filters all have a ‘max flow rate’ specification.
How long do fluorescent bulbs last?
Most bulbs have a operational life where they will provide ample ultra violet radiation and then begin to drop off in terms of performance. Twelve to fourteen months of operational life is common. After that you’ll likely want to replace them for improved performance.
Why is a slower pass rate better for algae?
A slower pass rate may help expose the algae to the light a bit longer and this can make a difference in performance. Normally some type of restriction valve can be put inline and help with this flow rate control. You may find that some uv lights come with several suggest flow settings.
Can string algae be damaged?
In contrast, string algae won’t be affected because it can’t pass through the tube and be exposed to the ultra violet light, which does all of the damage. In the case of green water, this discoloration can vary in a pond and the degree of just how green and dense it will get is totally dependent on how many little, ...
Does a slower flow rate sterilize water?
On the other side of the flow rate coin, a slower flow rate will provide a sterilizer effect on the water. A more thorough eradication of all affected elements will be made because of the longer exposure time to the ultra violet light.
