You are much too good a hobbyist to just accept what others do. If It does not make sense to you then ask questions and research some more. If you do not understand a concept and just pass it on to others no one wins
Just for the record I go with this time line for ick it is what Julian Sprung presented at one of our club meetings as something agreed on by Mote Marine lab. Here in Fl.
Parasitic stage 3 to 7 days
Free swimming stage (after falling off fish) 18 hrs to settle on some surface
Reproductive stage 3 to 28 days
Free swimming stage (to infect fish) 24 to 48 hrs
If we acquire a fish that has just been infected the total time to once again infect the fish can be as long as 38 days now that’s about 5 weeks. there is also the chance that we introduce ick in its free swimming stage via transport water when we acquired the fish so add two more days to the time line. This is why IMO when I QT and treat for ick I treat 6 weeks. We have to remember depending on what we use to brake the life cycle of Ick they are only vulnerable in the reproductive stage (hypo) free swimming stage (copper). As far as ick always having to be visible, this is not true. Your fish could have the parasites deep into its gills and not be readily seen. In this case the hobbyist does not treat in the QT until the parasite multiplies to numbers that the infestation is viable on the fish.
On keeping a tank fallow. (Fish-less ) if you go with my time line and a the parasite falls off the fish as you remove it to your QT you need to keep it fish less from free swimming to free swimming or at least 5 weeks ( again going by the time line I use. BTW I like to add one more week to the fallow state.
Good stuff!
I guess I still don't understand why you need to add up all the stages of the life cycle when two of them are what happens while its on the fish. You've removed the fish from the system so it seems like you wouldnt count those two stages. only the ones that involve once the cyst has dropped from the fish and the free swimming stage. I guess its irrevevant since your timeline says that the reproductive stage is up to 28 days which is the majority of your time line. which is way off from the link I posted.
Cool, So Ive gotten 4-6 weeks as a good rule, the longer the better as long as the fish seems to be taking it well.
and the freshwater dip is kind of a personal preference. I think I'll start doing this in the future since it seems like a good idea and doesnt seem to hurt anything.
