Agreed. The bacteria we tend to focus on is on the surfaces of media (rocks, sand, plastic, pellets), or in the mucus of fish and coral.

Some of this naturally dissolves into the water column, but it's not a substantial % of impactful population. If it were, our skimmers would likely remove them as efficiently as the UV would kill them.
