    No, it will likely kill some free-floating parasites (and lots of beneficial things BTW). if you do the math, all free-floating parasites are not necessarily killed by UV filter, ever, regardless of the flow rate and power. It will depend on the rate of reproduction. Remember, things that kill fast may reproduce fast.

    Spotte et al. 1981 Pathogen Reduction in Closed Aquaculture
    Systems by UV Radiation: Fact or Artifact?

    UV has been looked at fr decades in the aquaculture industry and is mostly considered to be not worth it, for well understood reasons..

    Pathogen Reduction in Closed Aquaculture
    Systems by UV Radiation: Fact or Artifact?*
    Stephen spottel and Gary ~ d a r n s ~
    ' Sea Research Foundation, Inc., Mystic Marinelife Aquarium, Mystic, Connecticut 06355. USA
    Department of Mathematics and Physics. Thames Valley State Technical College, Norwich, Connecticut 06360, USA

    ABSTRACT:
    Differential equations were used to set a theoretical upper limit for the efficacy of UV radiation in 3 hypothetical aquaculture systems: (a) a plug-flow system, (b) an idealized closed system with no influx of pathogens, and (c) a conventional closed system in which the influx of pathogens is continuous. The equations demonstrate that, in a conventional closed system, the mass of pathogens never reaches zero even if the UV sterilizer is 100 % effective. This suggests that agents such as UV radiation, which do not form persistent residuals, may be incapable of preventing the spread of waterborne pathogens in systems that are recirculated. Use of UV radiation in aquaculture is most effective in sterilization of raw water supplies and discharges lnto receiving waters, both of which are singlepass applications.

    +1 I agree with Corailline to kill of that many that fast must have been something super toxic

    Some of the fish were skinny and There was a cow and box fish in the pic. I have to agree that some of the fish got poisoned and some starved possibly.
