Frequently asked questions
What does and ultra violet clarifier do?
UV Clarifiers clear green water which is caused by single celled green algae and prevent it from returning
Where do I install the UVC?
Usually the UVC will be the first piece of equipment after the circulation pump. On a pump fed filtration system this means the UVC will be installed before the pond filter, and on a gravity fed filter after the circulation pump that returns the water to the pond.
What is the length of the power cable?
The length of the power cable for UK models is 2.2metres.
How often do I need to replace the lamp?
We recommend changing the lamp at the beginning of each year.

reducing-sleeves-imperial-pressure-to-waste-pipe
The 110watt professional UV has no fittings supplied. It requires 2" solvent weld pressure pipe which can adjusted to suit your personnel requirements.
Do the units come with bulbs?
Yes, bulbs and quartz sleeves are included in the box when you purchase an evoUV.
Are the bulbs and quartz sleeves pre-fitted?
No, we encourage the user to gain experience in fitting the UV bulb and quartz sleeve, as they will need to do it every year in the future when they replace old bulbs with new. There are fitting instructions included in the user manual.
Are UV rays harmful?
Yes, never look at a lit bulb as it can damage eyes and skin. To check if a bulb is lit up, view the closed unit at night. UV protective fittings will glow in the dark, indicating that the bulb is connected properly, and working.
What is a quartz sleeve?
It’s a tube that looks like it’s made of glass, which separates the pond water running through the unit, from the bulb. It’s very delicate, like glass, and should be handled with extreme care. Quartz sleeves should be cleaned regularly to ensure that the UV rays can shine through it, and do their job on the pond water. A dirty quartz sleeve will negatively affect performance. If a quartz is cracked or chipped, it must be replaced.
Why is there no plug?
evoUV adheres to UK pond equipment laws, and requires that it is wired into a safe, compliant, outdoor electrical system, ideally with an RCD cut-off. If you are unsure, consult a qualified electrician.
My green water isn’t clearing. Why?
Check that bulb is connected properly, and that the unit is wired in correctly, and on. UV should be on for 24 hours per day. Consult the recommended flow rates on the packaging. If water flow through the unit is too great, the contact time with the UV rays may not be long enough. Slow down flow with a controllable pond pump, or a ball valve. Check the pond volume calculation to enure that you have the right size of unit. If unsure, always go bigger. Check the age of the bulb. A UV bulb needs to be at its most effective from March until September in the UK. Install a new bulb every March. Always combine UVC with effective mechanical filtration, to remove debris which would otherwise shade the bulb, and to capture dead and damaged green algae cells after they’ve been exposed to the UV.
What replacement bulbs should I buy?
Evolution Aqua distribute and recommend Osram, a world leader in UVC technology. Obtain these from an authorised Evolution Aqua dealer.

Yes, all The evoUV clarifiers are suitable for saltwater, the Aquarium UV Sterilizer is made specifically for marine aquariums and is available in 15 and 25watt versions with additional fittings for connection to typical aquarium circulation pumps, however if you require a larger unit all the pond clarifiers are suitable for saltwater
