Hypo Salinity Display Tank?

[MrTuskfish]

This seems to be a good article on Osmotic Shock Therapy and gives guidance on long term use or not:

Thanks! I started hating "research" during the 1st 6 months of my chosen career. A good article; but 6 years old. The article implies that OST (hypo) works on velvet & brooklynella. I believe this has been shown to be false. Personally, I've come to think that hypo just fails far too often. Probably hobbyist error, especially noobs, but strains of ich could be adapting....who knows.

WARNING!!! DO NOT TRY THIS AT HOME!!
If I was honest, and I usually am, I'd admit keeping FOWLR tanks at about 1.017-1.018 until just a few years ago when I went to a central system for all of my tanks. Katrina took a lot of long-lived fish (including many "tough to keep" species that hadn't seen a SG over 1.018 for many years.

Yes, many of the disease treatments found in hobby papers are out of date or were never good to start with. You really have to look for the specific science in articles and trace them back to actual studies for them to be much use. This to me is a bit of an antidote to some of the incestuous information loops that exists in the forums.

If you've caught and HT'd with hypo twice, have you considered a last ditch effort of HT with copper before moving to something more drastic or that has more a "documented" success rate? I'm just wondering how open you are to another treatment method at this point. I can imagine the level of frustration you must be at having done it "right" twice, only to see the ick return.
The thing with hypo in your DT. If you do it, its going to be really hard to be confident in adding anything or upping the SG, just because you've had problems with hypo before. If you feel like you could feel confident in the state of the tank in doing it, it doesn't seem it could do terrible harm if done properly... but if its going to sit in the back of your mind, bugging you and keeping you from moving forward with the tank... well, it doesn't sound worth the effort to me...

Besides hypo and copper what other options do I have. Hypo was easy with a tunze osmolator 3155. I used copper before trying hypo and while I believe if works its difficult to test for, IMO. If hypo for my display isn't a good option what about using some sort of treatment designed to treat ich?

There are three treatments normally
hyposalinity - http://www.reefland.com/forum/marin...e-treatment/21830-hyposalinity-treatment.html

Copper - http://www.reefland.com/forum/marin...ment/18915-copper-treatment-use-problems.html

These happen to be my favorite links to procedures for treating using the above methods. It should be noted that in both cases, the slightest deviation or contamination will result in failure.

Tank swapping ( I so far have not met anyone for which this was successful in treating a verified case of Ich). I have met several people who either ultimately lost their fish or switched to one of the other methods. There might likely be a procedure on Reef Central for it.


There is another treatment for when you have confirmed that copper doesn't work: quinine sulfate. I do not know the procedure for this, but here is the thing, if you actually had a case of cryptocaryon that is copper resistant which is when quinine is used, it all likelihood the fish would be dead by the time you figured out that you had ich in the first place. My understanding is that it may be difficult to treat with, but I have no first hand experience with it. All known copper resistant cyrptocaryon have about a 24 hour period from symptoms to death for many species.

Copper resistant ich?? No such thing. Quinine sulfate is used for fish that are sensitive to copoer.

hmmm...I will bet good money that just came off the top of your head with zero research what so ever. I have no problem with people disagreeing with something I put out, but you better be able to back it up or I will call you on it.
Its a simple google search, please be my guest. I will argue with you when you have gone to the trouble to research about any number of things on which the work was based, but you have nothing.

Op, interested to hear what you ended up doing?

Op, interested to hear what you ended up doing?

First off hello,,i'm new to this forum but not the hobby ...

I would really like to know how its going also..
I came across this thread in a google search(and glad i did) because i have a similar situation and i was getting tired of reading the old outdated articles like noted above by Mr. turkfish ..
I have used hypo in the past with success on fish with visible ich ,,but most recently after QTing and adding the new guys ich did indeed appear on them after a few days ..
I am actually thinking the DT has never been ich free and the older fish were just able to fight it off while showing no signs ,not sure though,maybe the new fish carried it (QTed for 4 weeks)..I do want to treat the DT with hypo because i have no way of QTing all my fish ..I would need a 125 gallon QT for them..Also i have a puffer and i'm pretty sure they can not be treated with copper(correct me if i'm wrong)..
Just curious to see how its been going for the OP..
