I installed UVS in my 2 tanks sometime in Feb. this year, also added medication without knowing that certain medication used could be lethal. Guess those medication that I used were not lethal........but just wondering if the effectiveness of the medication was affected by my leaving the UVS on! |
bro..I will turn off the UVC during medication...
many medications can be "denatured" by the UV light, so the sterilizer should be turned off when using medications, especially chelated copper treatments. The UV light will "break" the bond of the chelating agent, & the aquarium will have a sudden, lethal concentration of ionic copper.
