Hey guys, I have the 24W Green Machine UV sterilizer running 24/7 on my tank. I'm wondering when do we know when these things fail? I'm curious if there's a point that I should remove it and add a lifegard or alternate UV plumbed to my system. Other threads have mentioned rust from these green machines as well. I've probably had mine a good 6 months by now.
What should I look for when its time to replace this one with a new unit?
