Q. Where do I install my UV?
A. The best place to install your Aqua Ultraviolet Sterilizer
is after the filter. If an after the filter installation is
not feasible, your sterilizer can be installed before the
filter, but it will take a little longer to work. If installed
before the filter, be aware that a small rock passing from
the pump can break the quartz sleeve. It is recommended that
if you install your unit before your filter, you check the
UV periodically for any water leakage due to a broken quartz
sleeve. Be sure to have adequate pre-filtration to prevent
breakage. (Broken quartz sleeves and sub- sequential damage
caused is not covered under warranty.)
Do I have to turn my UV off when I clean my filter?
A. Yes, but only if the chamber is drained or if the water
will remain at a stand still for more than 30 minutes. Note:
These units are water-cooled and should not be run without
any water in the system or, if full of water, for not longer
than the recommended time. This can cause extensive damage
to the unit.
What should I expect after my UV is installed?
A. If your Aqua Ultraviolet system is installed after the
filter and is properly sized the water should be clear in
3-5 days. If your Aqua Ultraviolet system is installed before
the filter the water should be clear in 7-10 days. The green
algae on the sides and bottom of the pond will not disappear,
this is normal in a pond. The UV doesn't control this type
What's the difference between a sterilizer and a clarifier?
A. As a sterilizer, your Aqua UV system will keep your pond
or aquarium water crystal clear in addition, you will have
the added benefit of bacterial control which will help keep
your fish healthy and happy with less risk of disease.
As a clarifier your pond will still have a green tint to
it, unless you have 50-75% plant coverage or your pond is
in full shade.
Do I install my UV vertically or horizontally?
A. You can install your Aqua Ultraviolet system either way.
What should my flow rate be on my pond or fresh water aquarium?
A. The optimum flow rate on your pond or fresh water aquarium
is to turn over once every hour or a minimum of once every
Should I bypass part of my water through the UV and the
rest back to the water supply?
A. No. Our UV was specifically designed to handle high flow
rates for easier installation and the best water quality.
Is this unit submersible?
A. Not this specific series.
Q. Does the UV light have any residual effect to the fish?
A. UV only affects what passes through the chamber. There
is no residual effect from UV light. UV is used as a control.
Q. Does the UV kill good bacteria?
A. Ultraviolet light does not discriminate about what it
destroys. If good bacteria passes by the light it will be
destroyed. Good bacteria are colonized in your filter, along
the sides and bottom of your pond. The only time it will
be affected is if it becomes free floating. All the bacteria
in the filter is safe because UV has no residual.
