Wait, one last question. What should I look for in a oregano oil. I ordered one, but I can cancel and add a different one if need be.
also, won’t the remaining oil kill the bacteria when I re-add the filter media?
Yes, it is external. That's why I suggested carvocrol. It will work both internally and externally.
The oil if soak in food will be eaten to treat internal bacteria. Add some diluted oil into the water column for external treatments. Doses can be found in the Disease and Diagnostics post.
Yes. But it's not like using carvocrol oil. Oregano leaves just aid in the process of using carvocrol oil.
Give it 3 days after treatment. And note: you might want to add a second dose 2-3 days after the first. So wait until you finish all repeat doses of carvocrol oil before adding the filters back in.
In case you didn't pick it up. The source of the info from the site you posted is our very own Diseases and Diagnostics post (see the disclaimer section in the link you provided).
The info here is more up to date.
You will need to treat the whole tank with Carvocrol oil, if you have a bacterial infection. Just save as much beneficial bacteria as you can before adding the oil. Carvocrol oil is very soluble, so it will mix in the water well.
Carvocrol oil isn't cheap, so hopefully we are treating the right ailment. Assuming it is bacterial in nature and not a water parameter issue. As I said, the pictures provided were too low in resolution.
I looked at the one here following the original site I posted. I am unable to quarantine to use oregano oil. And isn’t the bacterial shell disease external. It would be nice to attack both....
If it were your tank, how would you attack this? I feel more confident that it is, at least in part, the chitinolytic disease.
I could remove the HOB and one of the sponge filter sponges. The sponge I can put into the smaller 5 gallon with the fish to keep it seasoned, while the HOB can simply be turned off. How long would I then wait on the oregano oil to work before adding the filter media’s back in?
Hey, I just thought about Something.... I have some organic Greek oregano growing right now in my herb garden. Would those leaves work, and can I add the leaves without killing the filter bacteria in the tank?
