FAQ
How do I know when the bulb is dead?
There is a GREEN LED on the control box. If the LED is ON, it's good. When the LED is OFF, it's time to change the UV bulb assembly (or change the UV unit for Clip-On GKM3W).
How long does the unit last in service?
UVC bulbs typically last about 6-9 months in constant use. Some bulbs can last up to a year. To lengthen the service of your bulb, we suggest once your water is sparkling clear for 7 full days, start using your UV on a limited as needed basis. Run it with your light timer or only on weekends, etc.
Why is the flow rate so slow?
Slow flow rate together with our ZIGZAC flow design (inside the housing) is to maximise exposure time.
Is there a way to replace the bulb?
Just like any other UV system, the bulb itself is disposable. The difference between GKM and others is that we replace the lamp together with its housing, so we make sure the seal is 100% and avoid UV housing deteriorate over time. Prices for these replacement bulbs are reasonable.
​
How come my bulb looks old with dust all over it?
If you notice a slight whitish powder on the surface of your GKM, simply rinse it off. This powder is due to the special high-performance plastics we use that withstands the intense UVC bulb.
Does Mini GKM3W really come with 2 plugs?
Yes, 1 for the pump and 1 for the UV assembly, since our UV bulbs are 100% sealed at the factory, making it easy for consumers.
