There is evidence that longer term exposure to copper will damage the tomonts to the point of not being viable. This typically takes 15 to 20 days from what I have read. So in theory, after around 27 days there should be no viable tomonts left in the system which is why you can remove the copper at this point.I understand the removal after 14 days to a clean QT and a further observation period. If you check everyday with the Hanna checker to make sure you are at therapeutic levels, which benefit is there for a 30-day copper treatment?
After a 30-day treatment, do you also transfer to a clean QT for further observation? If not, don't you risk reinfection due to remaining tomonts (which can last up to 72 days) after removing the copper?

I wish I could. I lost access to them (paid studies) when a co-worker moved away. I wish I had saved a copy to my computer.Can you point me to the studies you read on copper's effect on tomonts?

I haven't read anything about copper having any impact on ich or velvet tomonts.
So the 30-day treatment effect on tomonts is based on anecdotal experience?
Or a study I have not read.
30 days of therapeutic copper/Chloroquine works in most instances because there have only been a few documented cases of ich theronts taking >30 days to excyst from their tomonts. However, transferring the fish to a different QT after 14 days of therapeutic copper/Chloroquine is a more reliable method IMHO.
That is my preferred method. Of all the studies I have read and didn't save, the one that talked about this issue is the one that haunts me. I've spent hours searching for it again and can only find rather vague references on the issue.Thanks. Looks like I'll be doing a 14-day treatment then transfer into a new clean QT.
I just got a copy... reading through it now. Not conclusive, but a quick glance shows it as very interesting.@Brew12 I'll try to get a hold of it.
