I don't necessary agree with this method for several reasons.
1) ICK will live in your tank for a good while without host
The average time frame for C. irritans is about 40 days without a host and upto a year with a host (that's taking into account the fish live)
& just removing the fish alone is not removing all possible host for ICK.
There is only one host for this parasite, teleost marine fish.
2. Stress in catching fish will also help weaken them farther.
True but if done properly, stress can be minimized. After lights out and using a plastic container as apposed to nets for instance. Time is the greatest factor in stressing the fish, not simpley the act itself. If you spend a good amount of time chasing a fish around a heavily stocked tank you are bound to have problems. If properly timed and conditions made optimal for it's capture, the time spent is much smaller and the stress lessened to a great degree.
3. Hypo-salinity in QT is good but what about the rest of the main tank.
If the main is left without a host, that being fish, the parasite cannot complete it's life cycle. Given enough time to pass the tomont will eventualll excyst and the theronts will perish. I know many suggest just 4 weeks but if you consider all the stages and possible time frames, the absolote least should be 6 weeks.
although treating fish before adding to a tank in the first place is a good idea, it still not a guarantee. As far as treatment you can read a ton of cures & reasons fish get ICK, each case will be different
I would disagree with both of those statements. If you put aside hobbyist "experiences" and look solely at the provable evidence surrounding this parasite, it is easily beaten and can be done effectively 100% of the time. Hobbyists may have many popular remedies but there are at this point only 3 proven cures. Hyposalinity, copper and the 4 day transfer method.
but while having many tangs I find three things that was very successful in preventing it. One quality water, two stress (water quality can cause higher stress, also aggressive fish mates) & three not proved but man from what I've seen first hand the garlic.
Stress is a factor in any animals health but to suggest it can trigger a parasite event such as this is simpley not true. Given what we know about C. irritans and has been scientifically proven, it cannot simpley manifest itself from nowhere. True garlic is a powerful antioxidant but in using it for this type of application, there is no way of knowing what amount is effective, for what time frame, at what level of theront densitity does it become less effective, would garlic continue to aid a fish with a supressed immune system, how would heavy daily doses affect the liver and kidney..... etc, etc.
It is always a good idea to do some searching & reading on the subject first hand, get to know what your dealing with, please do a search on ICK.
Hehe... on that we agree...
