I don't know what you've been reading, but it's wrong. The fish will be fine at hypo for the 4 to 6 weeks that you need for treating ich.
Takes prolonged hypo of several months to cause any problems with the fish
yeah i'd love to know who either made that up or is spreading it around, as no one's ever shown, or established, that the hypo treatment/protocol as should be done by hobbyists is in any way harmful to fish either short, or long term. there's simply NO evidence for that.
it's been (recently) postulated, btw, that sw fish (or many of them) may have evolved from fw fish, and not the other way around.
ICH in 125g reef tank
ICH in 125g reef tank
What do people do that have larger tanks and EVERY FISH in our 125g saltwater tank has ICH? My husband and I moved all of our inverts and corals out last night and put them in our smaller 45g with our 2 anglers. For some reason I was thinking we could do hypo in the 125g with the fish that have ICH, which is 16 fish total. But from what I am reading it sounds like we would have to either remove the live rock and sand as well or put the 16 fish into a QT tank, which we do not have.
What options do we have? The reason all of our fish are sick in the first place is because we had a power outage from an ice storm about a month ago. The first 3 days was hell on earth as my husband and I both were recirculating the water in the tank by scooping it up in cups and pouring it back in at a high level. We did this every 30 minutes to try and get oxygen running through the tank. We also heated the water from the tank in pots on the fireplace to at least keep the temp at 75, which is the highest we could ever get it. By the 4th day we were about to have a generator delivered to us. But the stress from all of this was just too much. We lost our Flame Angel and Six Line Wrasse and the remaining fish now all have ICH.
Also, I did start out treating the ICH with Metronidazole and Focus mixed in with their food and garlic. That was when I just had a couple of fish with ICH. But that did not work and as I stated earlier, all of them are now sick.
I would appreciate any help!

gag.... my DT just got ich... I just caught all my fish and put them in a hospital tank.. Thinking of doing hypo but might do copper.. I have two angels though, so I'm not sure if copper is the right move.. I really like my regal angel and i have a potters angel as well.
Hmmm..
So if I do hypo, I go to 1.09 for basically 8 weeks? How often do I need to do water change? This is a bare tank with just pumps to bring in air.

I brought this up in a different thread and I'm sure it is mentioned somewhere in here, but is there a quick answer to why there is no standard recommendation to increase and maintain the Hypo water KH to around 7dKH or whatever? If you just put in enough salt to bring to 1.009 you are likely to only have a 3 dKH or much less...
125mph - 4-6 weeks is all that is necessary, but shouldn't hurt anything to do 1.009 for 8. Maybe do 6 weeks at 1.009 and 2 weeks at full before moving them over. You can do water changes however often you like. If you have just a couple fish in a reasonable sized tank, you can get away with very few water changes... vice versa applies as well. Get one of those suction cup ammonia testers and keep an eye on it as well.

So long as you have enough buffering capacity to keep the pH 7.8 or above, you don't really need to worry about the alkalinty measurement for fish.
I believe I have noticed another benefit of Hypo - No more aiptasia in my sump rocks. It was pretty thick down in the sump. 3 weeks of hypo later - no more signs of aiptasia. I have a big tank - 360, so I took all the LR, inverts, and crushed coral out of the display, all the snails I could find in the sump. The fish are doing well in Hypo.
Hypo salinity question. 30 days from the last observed cyst to raise the salinity back up (for me would be about 45 days), 72 days to put the rocks and inverts back in? Or should I keep the hypo for 72 days? I don't want to go through this again.

I read recently that the marine ich only be played 11 times in our aquariums and then degenerates genetically speaking, the year he dies,,, so yes, only if we put anything during that time at the aquarium, no fish, no rock nothing, that is to keep out any new strain
OJO this is one reading I got on the web, I do not know if it's true, I come to ask the experts here
regards

In a lab setting, utilizing only one species of fish, researchers have only be able to keep single isolated strains going for 11 generations. Keep in mind, in our aquaria there is little guarantee that any ich infestation is only a single strain. It's quite likely that on any given fish that more than one strain could be present at the time of introduction. Multiple fish with multiple introductions greatly increases the probability that multiple strains of ich have been introduced to the tank.

Billsreef Greetings, I am aware of what you mention, but there it is the detail, if no fish is introduced to said aquarium or rather nothing at all, if possible for this to happen, or given the variety of fish is highly unlikely that in a year the population of ich is reduced to a single strains??
I mean if it is true that in a controlled environment can know if genetically degenerate??
I seek encouragement of discussions, only to learn

Injuries and hyposalinity? Does it affect the fish's slime coating?
I've only used hyposalinity one time on a batch of fish and I noticed that one fish had an invisible wound, a scratch on his body, which became apparent one day into acclimation. Under normal salinity, I'm sure the scratch would've healed, but while I was bring the salinity down, I think water was flowing into the wound (or the fish was losing salts out) and the scales puffed out and away from the skin, turning visibly white.
At the time, I was treating 4 damsels, and 3 other fish (yellow tang, bicolor blenny and strawberry dottieback) in the tank and lost that damsel. About 2 weeks in, of course damsels being damsels, there was infighting and I noticed the smallest one being beat up, so I separated him into a floating net. I noticed that after a few days, his nipped fins weren't healing either, and appear to be breaking off. It looks to be like he wasn't producing the normal amount of protective slime coating and he died on week 3.
So, is this a hazard of hyposalinity? How do I remedy this if fish aren't though the quarantine time frame? Use stress coat?

Never noticed an effect on slime coat one way or another. From what your describing, sounds like an infection that was not effected by hyposalinity. Likely bacterial infection of the injury, which would require antibiotics to treat. Nothing to do with hypo.
Missed this earlier.
It's kind of an open ended question. Once the tank is stocked, with no introductions of new livestock of any kind, the ich strains in existence will eventually cross breed to the point that inbreeding produces that single strain. Just how long that takes will depend on variable factors, such as how many strains you start out with. At this point, without doing this as a highly controlled experiment, the time line is simply a best guess scenario.

Hypo In Display Tank
Hypo In Display Tank
Hi All,
I have also posted my question here (http://www.reefcentral.com/forums/showthread.php?p=22849593#post22849593) but thought I'd see if anyone would want to answer it on this thread as well.
We have a 300 gal FOWLR tank and have 3 raccoon butterflies and 1 blue and gold rabbit fish. We added our raccoons about 1 month ago and they were QTed for 8 weeks with no signs of Ich. We are noticing ich in our tank as of a few days ago with the butterflies being the last addition. We believe our best option would be to do hypo in our DT as we do not have any inverts (just some pink polychaete worms, white baby snails, clear flatworms and feather dusters) along with the live rock and live sand.
As long as we keep up with water changes and watch for any ammonia spikes, we should be fine right?
Thanks!

I think I am going to start this today. I had an ich outbreak a couple days ago and I was going to wait an see if the fish can get through it because my water params are very good and they are still eating like beasts. However, the ich is getting worse.
I have only a FOWLR with barebottom. If left in hypo long enough will this kill the ich that drops onto the rock? I have about 120 lbs in a 90 tank and can't really move it.
Also, when dropping the salinity down should I just drop it with straight RO water or water with like a little salt in it?
