Can someone please tell me how much hydrogen peroxide to add to my 125 gallon tank to get rid of any ich or velvet or other disease that is in my tank. I have live rock and xenia and dragons breath with a twin spot wrasse and 12 yellow tail damsels. Last summer I lost 3 fish to ich, the twin spot wrasse and a green bird wrasse were the only survivors. Four months later I added 16 damsels and my green bird wrasse died. It was not ick but something killed it after I added the damsels. I noticed a few of the damsels had white patch on them. This spring I intend to add more fish but first I want to eradicate the parasites that are in my tank that could cause any new fish to get diseased. Thanks

Lots of people here are proponents of copper, hyposalinity, or tank transfer method.
Personally, if I did this each time I saw ich, I would leave this hobby. "Aint nobody got time for that"
Plus, my set ups are stable and I typically handle parasites with 3% Hydrogen Peroxide.
1 ml per 10 gallons. I have used up to 4x this amount safely in FOWLR setups. I have never in my reef tanks. I know that star polyps and mushrooms can handle 4x this dose regularly.
I would also dose this for 3 weeks. Daily. If you have a fish that is suffering badly and can easily catch him (at night for instance so you dont stress them out trying), you can give baths for temporary relief... although you'll need to also dose the tank to slowly kill it off.
For baths, 30 minutes and I do 7-8 ML per gallon of water used for the bath. If I recall, this is somewhere between 60-70 PPM. 5 ML per 2 Liters is 75 PPM. 3.75 or so per 2 liters is 50 PPM. There are 3.875 or so liters in a gallon.
Anyway, good luck. If ich is an issue because of high nitrates or other things out of whack, this will likely not fix the issue because the issue is the poor water parameters.
Also, they are suggesting that you take the fish out and house them somewhere else for treatment for 72 days, keeping tank empty for this time.
I have found this not to work, or too stressful on the fish and a LOT of work.
Disclaimer: Although I have not had any issues with hydrogen peroxide, it is still not yet known what affects it may have on inhabitants, particularly invertebrates and corals.

It's called using a separate Quarantine tank. Not to be a downer, but patience is key in this hobby. As 3fordfamily said, if he would leave his tank fallow (which is what you're suppose to do) for 72 days then he would be out of this hobby. Not sure he is in it for the long run, but diseases will wipe out tanks sooner or later. I've lost 9 fish in 2 days because of diseases. Left the tank fallow for 72 days while the last 3 fish were in Quarantine. Almost 2 years later the tank is disease free. Just trying to help and save you the headache I went through.

I have been in the hobby over 10 years with at least 3 tanks at a time. Little trouble, but I also invest heavily in OVERskimming, I have MORE live rock than needed, and honestly I don't worry about parasites other than dosing Hydrogen Peroxide.
I used to take my stuff apart and panic and go through hell each time I saw ich velvet or brook but ended up killing more fish doing the "recommended methods" with stress than I did when I stopped caring and worrying so much. When I say stop caring, I assume that the presence of ich is because of overstocking, bad water params, or something else. I find the issue. Feed well. And 9/10 fish come out of it fine. All 4 of my systems have ich present. No existing fish show signs currently. Only new additions have any chance of succumbing but most pull through fine.
This is easier in larger systems, IMO as they're more stable.
In my time at the LFS, I also watched fish come and go. Fish that could survive in LFS water LITTERED with parasites (sorry it's LITERALLY statistically impossible to have an LFS system parasite free) for weeks. I bought these fish after a month, as it is evident that they can survive anything!
but you can say, for sure, that it kills ich? i wanna live in your world.
Now THAT would require a special entry permit. There is no peer reviewed published data on the effectiveness of hydrogen peroxide that I am aware of.

I would be very surprised if it did, I wouldn't take chances with it. That's why we have TTM, Chloroquine Phosphate, and cupramine... I don't think hypo should even be considered with the first three, all of which are easier than hypo. TTM is the go to 14 day ich iradicator with no meds... Thank you Steve:smokin:
you know, of course, that was said with tongue firmly planted in cheek.
maybe if the peroxide was mixed with a little ginger?

I always like it when you explain stuff to me. :celeb3:

They make cookies like that? Oh, you mean for the fish?

For the most I haven't done excessive quarantine or bothered to eradicate Ich from my tanks and I can't remember to have lost any fish to Ich during that time. But then I cherry picked my fish and stayed well clear of tangs and the like that easily get Ich and need rather big tanks to begin with.
If you keep only fish that naturally have or easily develop resistance against Ich and you pick strong and healthy specimen to begin with and put them into a healthy tank you may get away without eradicating Ich.
But if you want to keep a wild collection of tangs, butterflies and angels you better make sure no Ich makes it into your system.
I'm a big proponent of letting everyone make their own decision as long as they make an informed decision.
If someone wants to spend his vacation in Raqqa or Mosul, knowing what's going on there, well go ahead.
But don't start wining later if you end up a head shorter.

yes, dear. everybody knows ginger cures ich. i'm pretty sure it cures blown vertebraes, insanity, and cancer, too. the verdict is still out on stupidity.

Great. I have some of all of that, so ginger cookies it will be.
