What you are referring to is that in your system those fish perished. I don't know what system you run but I have posted mine and Paul his along with a few more and our fish don't secumb to itch. So my statement applies to my nconventional system. I cant comment on yours as I don't know of it. BTW have you read all the other posts myself, Paul and a few more have posted on the issue of itch and our systems?
Yes, I read some but not all the posts. I still stand by my statement though. Regardless what system you run, it still boils down to the individual specimen. Dont know any other fulproof measures other than the ones been proven with a great track record. Thanks!
