Classic Series – SL Series Sterilizers are perfect for both experienced and non-experienced end users, for both residential and commercial UV water treatment. UV Sterilization is versatile technology used for disinfecting water, other opaque liquids, hard surfaces and air. Using the same germicidal rays as the sun, but hundreds of times stronger, UV offers a reliable, cost effective, environmentally friendly alternative to chemicals and their resulting biproducts.
UV Sterilization is a purely physical process so it doesn’t alter water’s chemistry, taste, smell or pH.
The SL Series is compact and lightweight, ideal for large ponds, aquariums, and water features. SL Series units are lightweight units designed for maximum UV effectiveness, and offer a hybrid mix between having a needing something bigger than a Classic and smaller than a Viper Series.
*Aqua Ultraviolet does not recommend utilizing Wipers with Salt Water and if utilized in this manner will void warranty on the Wiper parts.
Where do I install my UV?
The best place to install your Aqua Ultraviolet Sterilizer is after the filter. If an after the filter installation is not
feasible, your saltwater or freshwater 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. (A broken quartz sleeve and
any damage caused by a broken quartz sleeve is not covered under warranty.)
Do I have to turn my UV off when I clean my filter?
Yes. The SL Units are completely water cooled, and should not be run without water or when water is at a stand
still for any length of time. This may cause extensive, irreversible damage to the unit and is not covered under
What should I expect after my UV is installed?
If your Aqua Ultraviolet system is installed after the filter and is properly sized the personal or commercial UV water treatment should take full effect 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 of algae.
What’s the difference between a sterilizer and a clarifier?
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
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?
You can install your Aqua Ultraviolet standard SL system either way. Units with the wiper option should be
installed horizontally to keep the wiper seals wet.
What should my flow rate be on my pond or fresh water aquarium?
The optimum flow rate on your pond or fresh water aquarium is to turn over the volume of water once every
hour or a minimum of once every other hour.
What should my flow rate be on my salt water aquarium?
Your minimum flow rate should be 3-5 times the volume of water per hour.
Should I bypass part of my water through the UV and the rest back to the water supply?
No. Our UV was specifically designed to handle high flow rates for easier installation and the best personal and commercial UV water treatment effect.
Is this unit submersible?
Not this specific series.
Does the UV light have any residual effect to the fish?
UV only affects what passes through the chamber. There is no residual effect from UV light.
Does the UV kill good bacteria?
Ultraviolet light does not discriminate about what it destroys. If good bacteria passes by the salt and freshwater UV sterilizer it will be
destroyed. The good bacteria colonized in your filter and along the sides and bottom of your pond are not
affected. The only time it will be affected is if it becomes free floating.
How often should I change my lamp?
Lamps should be changed after 14 months of continuous use.
Are all UV lamps of the same length the same wattage?
No. The power output of the lamp has nothing to do with its length; other factors like the amount of mercury it
contains and the power supply that feeds the lamp govern this.
