Q: Is this a disposable unit? A: UV lamps have a life span of 6-9 months in constant use. We do not recommend to use it 24/7 once the water is clear. If the LED indicator on the control box is OFF, it means you will have to replace the UV lamp assembly (AA09W-UVC or AA24W-UVC). Just like any other UV system, the bulb itself is disposable. The difference between AA and other brands 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 very affordable. Q: Why is the flow rate so slow? A: Slow flow rate together with our ZIGZAG flow design (inside the housing) are to maximize exposure time. Q: Can you make the sponge bigger? I have to clean it every 2 days. A: GKM is not an internal filter. You can try to put the UV system near the outlet of your existing filter, where the water is cleaner.
Q: How come my bulb looks old with dust all over it? A: 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 in the GKM.
