This is simply incorrect on all fronts.
If your tank has that much Pelagibacteraceae while running UV there is something very unusual about your UV setup. We've seen at least one case where there was a burnt out bulb. Flow rate issues can cause similar problems.
For the record we've never, never had 3-6 month turnaround and our current turnaround is 2-4 weeks. Its DNA sequencing, not CSI. Universities do this stuff on a 6-12 month timescale. But if you don't find it useful you are of course free to go elsewhere. Plenty of other clients, including university researchers, do find it useful.
False statements arent useful though, lets keep it factual.
