Yeah I swear the UV kills pests like Gnats, but why do some have to get sucked into the light and end up dead on other side on clear casing over LED pennel... THEY SHOULD OF LISTENED TO CRES!

The middle light is the UV light, don't worry, it's on. Of course, it says that in the instructions.....just saying.....

Soak some broken up mosquito dunk in filtered (no chlorine or chloramine) water and water the plants with it. I've never had a gnat problem since. That and I installed an intake filter.
