UV to treat PM?

[Stoney Mahony]

I have never had PM so I can't do any tests but the vast majority of protozoans are killed at ~200,000 - 240,000 microwatts/cm^2. Now if Barry is correct and this is a protozoan, I would think that a FW dip(to kill off most of them) followed by the use of correctly sized UV sterilizer should stop the protozoan from spreading to other clams and eventually cure the infected clam. Does anyone here have (now or in the past) PM and use a large UV that is capable of killing protozoans?

theoretically that could work but you cant guarantee that the protozoan will pass through the UV. you would have to have the clam in a tube that then feed the UV and even then the protozoan would have to leave the clam.

when i had PM i was using a large UV

Yeah, like Ich, I guess there wouldnt really be any way to assure the protozoan would pass through the UV. You could a put a UV on the return line from your QT tank and plumb that into your main tank. It would keep parameters the same without having to set up an entire different filtration system and it would make sure not to spread the PM. As long as you have the appropriate flow rate you would zap anything going through the UV. On a 10 or 20g QT tank, those UV doseges would not be that hard to hit.
