That said, my tank wears a seatbelt too. A very big seatbelt, because I value it and want to take preventative measures to protect it. Even if that protection is not a "Fix all" by any stretch.
It's a scientific fact that two known, very bad nuisances in our hobby, have a free swimming stage. Ich and AEFW. Am I guaranteed to get 100% of those free swimmers with the UV were they to be in the tank? No, but even if I get 50%, that's an improvement I'm willing to pay for.
A nice by-product is insane water clarity.
