Review on 🐠 Fluval In-Line UVC Clarifier for Enhanced Aquarium Filter Performance by Wendy Parks

I was so excited to add the Fluval UV light to my Fluval 107 canister filter. I ended up fumbling with the hoses for half an hour and finally installed this UV light is beautiful and neat. Powered on, everything seems to be working, the green LED is on. A few minutes later the red LED came on. I tried turning off the light and starting over. The same thing happened - the red LED lit up after 2-3 minutes. The instructions clearly state that a red LED indicates a permanent malfunction of the device. I'm getting a replacement from Revain and will update this review once I try the second UV light.
