Yes, thank you it very much goes to show my point. here is the qoute from the treatment paragraph.
"
[h=4]Treatment[/h]Given the variability the trophont stage (3-7 days on the fish), it is quite likely that at the time of the starting hyposalinity, at least some trophonts have already dropped off the fish and encysted. If hyposalinity is not effective (or not as effective) on these tomonts, they may be able to complete their divisions and produce theronts. As they may take 28 days (or even longer) to release their theronts, you would want to keep the hyposalinity going for at least that long. As discussed, hyposalinity is effective on the theronts, so leaving the fish in hyposalinity until you are sure all tomonts have completed divisions and released their theronts gives the best possible chance of beating the parasites. This requires maintaining hypsoalinity for at least 4 weeks, with 6 weeks giving more margin for error.
That covers treatment, now on to prophylactic use of hyposalinity.
Cryptocaryon is not the only parasite that can infect new fish and is also not the most deadly. The danger with prophylactic use of hyposalinity is if the fish are infected with something else, e.g.
Amyloodinium, you'll have to raise the salinity before you can start treatment - copper is more toxic to the fish at lower salinity because it is generally harder to control the pH. I would prefer to just quarantine the fish without treatment and be ready to treat them immediately and appropriately at the first signs of infection."
ok, so we are worried that a trophonts on the fish will ( and most like will, I agree) will drop off and encyst (tomonts) in the hypo treatment tank. Now these tomonts have been found to take 7 to even 35 days according to this article to mature and and become free swimming ( infectious stage) tomites. First consider that the trophonts can take up to 7 days to drop off, and now lets add the 7 days to the 35 days it has been noted for a tomonts to mature and now we have a protocal for a 42 day hypo treatment, don't we?
my point is that free swimming ich can't live in hypo and as stated, and as soon as you are at 1.009 there should be no risk of any re-infection from any hatched tomites because they can't live in hypo. agree??? so it really boils down to the only concern is the potential life span of the tomont (up to 35 days) and introducing the tomount back into the tank at normal salinty where it will continue its life cycle and re-infect the fish and/or introducing any freshly hatched tomites also is a consideration also.
so what about the tank transfer method to cure ich? here is one method
http://www.reefnation.com/tank-transfer-cs-marine-ich-cryptocaron-irritans/
so now lets look at my 80% daily water changes in a relativley bare bottom tank with nothing for the tomonts to attach to.( which decreased their chances at reproduction)
after 7days of hypo all trophonts should have dropped off the fish and any free swimming ich should not live, so again we are only talking about tomonts. If one day 8 I vacume 80% of the water I should by simple math be be ridding 80% of the tomonts.
for easy math lets say there are 1000 tomonts to begin with. I suck out 80% on day 8 leaving 200 behind.
on day 9 another 80% removal leaves 40
day 10 leaves 8
day 11 leaves 2.2
day 12.........0.44
now I don't know where that last half a tomont is hidding so i'm not sure I can suck him out, lol. but the odds are really in my favor for a cure at that point PROVIDING there are no hatching and live free swimming ich that are reintroduced to a ich-free tank.
I'm just saying...we can read all the studies we want and listen to peoples experience ( wich I always do) but sometimes you have to take all the facts from all the sources and then think for yourself and ask the " what if's as it applies and is supported by previous studies, facts, and experiences.
take red c here for example. I TRUST all of his experince and took very seriously his claim that its safe to use copper safe ( not the safest form of copper) in hypo and based on that experince may give it a try. ( I just don't like people being rude for nuthin)
In summary, I want to leave my fish in hypo for 42 days!!!! but I'm not going to.
