o and UV sterilizer bulbs do kill Algae as well as bacteria ! plant life needs the visable light spectrum mainly the reds - violet or 1700K-10000Kelvin ! im not sure where we would cat. the UV leds/tubes we use being that there just within the visable spectrum or the blue , green or even red leds/tubes as there not full or wide spectrum (sun light at high noon is about 5200 Kelvin and ideal for plant growth , alge growth although a plant need less) but i dont think they would be a big concern compared to say sun light from a nearby window or the light from a RGB monitor thats about 6500K that would .

Actually I found out that not only am I wrong, its that the wall is not even 1/8. I found out, much to my dismay, that the one I use has 3/32 thickness.
