Ahhhh. They’re not too spendy but I might tinker a bit with some stuff I have laying around. The bottom drawer of my gravity rig just holds outgoing H2O. I would need to shield it from killing the good guys living in the drawers above I bet."The particular wavelength of light that the bulb emits is harmful when it comes in contact with things around it. So when organisms such as bacteria, parasitic protozoa, and algae cells come in contact with the light from the bulb, their DNA is altered, ultimately causing harm and death to the organism. In essence, they are 'nuked.'"
After they are nuked they clump together and get filtered out by your mechanical filtration, but if you don't clean your filter pads regularly it will just add more decaying biological material to the system. Mine helped a lot in the beginning but now that my pond is established I could most likely turn it off and I wouldn't notice a difference.
