how long to wait for a fishless tank after ich?

you certainly could just do daily water changes while feeding sparingly.
keep in mind this is a laborous task,but will be necessary as NH3 will rise daily and possibly 50% changes will be needed.
the smaller the tank, the quicker it will rise.
 
I had an Ich outbreak following a power ottage. Hadn't added any new fish in months! Lost pwder blue,hippos, Majestic ,Chevron and others. I still have about ten fish, all eating and looking totally healthy.
Do you guys think it's necessary to wait 6 weeks before introducing any new fish?
 
Are you preforming hypo on these fish right now in QT? I don't understand if you are QTing them with hypo or what.
 
The remaining fish are in my 120 reeftank with all the parameters the same as before the incident. ph 8.2, sg 025, temp 80 etc

I'm still just guessing at what you want to know. So you are thinking that if you wait 6 weeks you won't have any more ich in the tank even though you haven't done any hypo to erradicate the ich? You're leaving info out here that would help us/me help you. What do you want to know?
 
What I want to know is since I can't do hyposalinity because I have many inverts in my reef, and it would be futile to try to capture and QT the remaining healthy fish. Would the most prudent approach be to wait 6 weeks and then start introducing new fish
 
Without doing anything to kill the ich you still have ich in the tank. Waiting 6 weeks will do nothing to take care of the ich issue in your tank. To get rid of the ich you must QT the fish and perform hypo on them OR use copper on them in hypo. You can't do hypo or copper on coral, live rock or inverts as it will kill them.

This must be done for at least 4-6 weeks in QT.
 
Err on the side of caution, it's worth it in the long run.

Think of it this way,
you have a fallow display.
You will eventually be adding fish again.
You will QT new fish
To QT new fish (now, and the next time you want to add a fish or several) - you will need a QT tank.

Starting today timeline...

set up QT system, couple of days?
getting the fish you want to start with ? One day to weeks?
Qt the fish, maybe do a hypo treatment - 6-12 weeks.

By the time you have fish ready to be transitioned into the display, the display will have been fallow for 8 weeks plus anyway, so don't worry about that being too long.
 
I have something to question over the large debate about ich. In regards to Nakamas question above for those who know abot ich with EXTENSIVE experience. Isn't it true if ich is still truly in the tank after it has remanifested itself through it's lifecyle rehatching hundreds of new eggs they would overcome whatever host thats left in the tank???

It doesn't make sense to me that folks say you still have ich in the tank...if they cannot host on a fish that means they die. right?... I mean simple logic to me... ich hosts on a fish, fish eats until the ich is so heavily infected onto that fish that it dies and then of course the ich free floats in the water column in search of a new host and bam process starts all over..right?

Please someone explain this to me.. Now I know if a fish is healthy it can ward off the ich which would make me think if it cannot host on that fish it eventually dies.. Like I said..it sounds like simple logic no host no ich. Now if fish has obviously lasted over a couple months time with no signs of ich I would say ich is dead not alive because they couldn't host. Please if anyone can elaborate with a real answer and not a lifecycle of ich because I know it's cycle process but that is not an answer.

Again I am only requesting this information because I read where some say it is hosting wihtin the gills but again their cycle process would manifest that many more even in the hundreds and they would take over the fish? or am I missing something. I recently for the second time in while enjoying this great hobby added you guessed it a tang, it got hit with ich FAST and died in 2 days. My current occupants are a sfe which I am not afraid of being infected but know it can happen(rare) and a gold striped maroon. The maroon is still doing prefectly fine with no visible signs and it has been 2 weeks since the occurence. I am not making a 3rd mistake especially knowing better that I shouldn't have made it a second time around by adding a QT no questions asked, but oh well it happened , water under the bridge.

Thanks everyone,

Nick

couple of days??????????

dude, its been four days for me and i still have no water in the tank. what a mess, its taking me too long to find a tank, check the tank for leaks, find asnwers to questions. i still need to figure out what i can afford to buy or get for biological filtration. only thing i got to spare is a canister filter. i bought the copper med kit and test kit. tonite i will have no time for any advancement to set the qt tank. it sucks knowing that im racing againts time while my blue tang is getting a little more of ich every day. i beleive my large yellow tang may have it.

my biggest worry is how much time will kich kill my fish?

i still have some questions like, what will my lawnmower bleeny and also a sand sifting diamond blenny eat it a bare empty tank, no substrate or live rock.


thanks,

in some instances yes; some others, not necessarily

correct, the parasite will die over time without a fish host, i believe the time will vary depending on strain and temp

ich hosts on a fish, fish eats until the ich is so heavily infected onto that fish that it dies and then of course the ich free floats in the water column in search of a new host and bam process starts all over..right?
well,, my understanding is the cycle does not quite happen in that progression. once it releases from the host, it does not search for a new host just yet. this is the stage where it will attempt to manifest itself by encysting on a hard surface. manifest itself over time and then release hundreds more to then search for host. also, not all parasites will release when host dies, some will not release and die within the fish. I believe they cannot continue the lifecycle on a dead host.


Please someone explain this to me.. Now I know if a fish is healthy it can ward off the ich
yeah, well here's the thing. not ALL "healthy" fish can avoid becoming infected. there are many some variables here that will not be consistent with all infested tanks. i'm not going to elaborate on all of them here.
which would make me think if it cannot host on that fish it eventually dies..
i'm also going to guess here that if for some reason the parasite cannot attach and burrow into the fish it will die. the parasite could be weakened or the fishes slime coat could be too thick or both.

Now if fish has obviously lasted over a couple months time with no signs of ich I would say ich is dead not alive because they couldn't host.
true probably most of the time,,however,,with certain fish, it cannot also be easy to observe outward signs of minor infections. especially if the fins are not infected.


I read where some say it is hosting wihtin the gills but again their cycle process would manifest that many more even in the hundreds and they would take over the fish? or am I missing something.
well,,perhaps. depending on the particular fish stocked this may or may not occur. Unfortunately, you cannot just lump all variations of strains and fish species together and say what the eventual outcome will be. I have seen many tanks with small populations of the parasite, yet the fish appear to be fine.(I presumed that their tanks have been mildly infested for awhile). I have seen many different situations in my own tank that seem to go against the "logic". What i thought would have been the case, sometimes wasn't.

I recently for the second time in while enjoying this great hobby added you guessed it a tang, it got hit with ich FAST and died in 2 days.
i find it rare(unless signs went unnoticed for awhile) a fish would die directly from ich parasites within 2 days. oodinium yes,,but very rare for ich.

good questions Nick,,I'm no expert, just been dealing with this directly for what seems an eternity. If you want any elaboration on anything, i will try to do that.

does the lmb eat prepared foods? i succesfully quarantined one that did(well,,there was a mishap of a different manner there) and one that didn't.
for the one that didn't i was able to have enough micro algae to grow to keep him busy,,that will be key..grow it anyway you have to.

the diamond could be a problem.. you may have to regularly add to the tank what it would find in the substrate. gl
 
thx so if in the future, i wish to add another sandsifting, how would i qt him if the tank had no substrate?
 
if you're pre-treating with copper:
you could put some substrate in a bowl place in small section of qt.
i think the amount of copper that will be absorbed from the sand bowl would be minimal. you need to test the copper concentration frequently anyway. just add a bit more if needed.
replenish the critters into the sand bowl for fish to sift through.
