Not sure where you are going with this. This list was just a list of what UV
filters kill and what UV dose is required to kill them.

No dispute - none.
It's just that UV's of this type are not the ones that are sold for pond
use. Whereas you can argue that UV is UV, the difference in what will be
"killed" is in wattage and flow rates. My (reasonably good) UV is a 40
watt
number rated for 3,200 gph. I push about 2,600 through it. It's for pond
use
and can not be compared to the ones you listed. Mine cost low 3 figures;
the
ones you reference cost mid 4 figures at the same flow rate.
