Aqua UV Classic FAQs:
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 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, but only if the chamber is drained or if the water will remain at a standstill for more than 30 minutes. Note: Running longer than the recommended time without water flow can cause extensive damage to the unit that is not covered under warranty.
What should I expect after my UV is installed?
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 does not 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, plus 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 the algae in your pond will be reduced, 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 it either way. The Wiper version should be installed horizontally to keep the wiper seal wet.
What should my flow rate be on my pond or freshwater aquarium?
The optimum flow rate on your pond or freshwater aquarium is to turn over the volume of water one time every hour to every hour and a half.
What should my flow rate be on my saltwater aquarium?
Your flow rate should be 3 to 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’s are specifically designed to handle high flow rates for easier installation and the best water quality.
Is this unit submersible?
No, not this specific series.
Does the UV light have any residual effect on 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 light it will be destroyed. Beneficial bacteria are colonized in your filter and along the sides and bottom of your pond. The only time those will be affected is if it becomes free floating and passes through the UV.
How often should I change my lamp?
The lamp 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.

They know their products
They honestly know the industry of all their products they sell. Ben answered all my questions for my pond. I look forward to working with them in the future.
I had an urgent need to replace my old Aqua Ultraviolet 25W device which sprang a big leak due to 20 years of continuous service. PlayitKoi reached out to thank me for my order and then stepped up to expedite a device the next day.
Ben was incredibly helpful with suggestions and clarifications. He wasn't interested in just "making a sale" as much as he was in making a customer. He gave me more than adequate 1:1 time with frequent follow-ups until my pond needs were met. Thank you Ben!
